### firstLine

    Component firstLine

  A relative positioning constant, that can be used instead of north, south, east, west or center. mixing the two types of constants can lead to unpredicable results. If you use both types, the relative constants will take precedence. For example, if you add components using both the `NORTH` and `BEFORE_FIRST_LINE` constants in a container whose orientation is `LEFT_TO_RIGHT`, only the `BEFORE_FIRST_LINE` will be layed out. This will be the same for lastLine, firstItem, lastItem.

### focusTraversalKeys

    Set[] focusTraversalKeys

  The focus traversal keys. These keys will generate focus traversal behavior for Components for which focus traversal keys are enabled.

    boolean newEventsOnly

  `newEventsOnly` will be true if the event is one of the event types enabled for the component. It will then allow for normal processing to continue. If it is false the event is passed to the component's parent and up the ancestor tree until the event has been consumed.

  See Also:
    `Component.dispatchEvent(java.awt.AWTEvent)`

### eventMask

    long eventMask

  The `eventMask` is ONLY set by subclasses via `enableEvents`. The mask should NOT be set when listeners are registered so that we can distinguish the difference between when listeners request events and subclasses request them. One bit is used to indicate whether input methods are enabled; this bit is set by `enableInputMethods` and is on by default.

  See Also:
    `Component.enableInputMethods(boolean)`, `AWTEvent`

### changeSupport

    PropertyChangeSupport changeSupport

  If any `PropertyChangeListeners` have been registered, the `changeSupport` field describes them.

### gridx

    int gridx

  Specifies the cell containing the leading edge of the component's display area, where the first cell in a row has `gridx=0`. The leading edge of a component's display area is its left edge for a horizontal, left-to-right container and its right edge for a horizontal, right-to-left container. The value `RELATIVE` specifies that the component be placed immediately following the component that was added to the container just before this component was added.

  The default value is `RELATIVE`. `gridx` should be a non-negative value.

  See Also:
    `GridBagConstraints.clone()`, `GridBagConstraints.gridy`, `ComponentOrientation`

### gridy

    int gridy

  Specifies the cell at the top of the component's display area, where the topmost cell has `gridy=0`. The value `RELATIVE` specifies that the component be placed just below the component that was added to the container just before this component was added.

### weightx

    double weightx

  Specifies how to distribute extra horizontal space.

  The grid bag layout manager calculates the weight of a column to be the maximum `weightx` of all the components in a column. If the resulting layout is smaller horizontally than the area it needs to fill, the extra space is distributed to each column in proportion to its weight. A column that has a weight of zero receives no extra space.

  If all the weights are zero, all the extra space appears between the grids of the cell and the left and right edges.

  The default value of this field is `0`. `weightx` should be a non-negative value.

  See Also:
    `GridBagConstraints.clone()`, `GridBagConstraints.weighty`

### weighty

    double weighty

  Specifies how to distribute extra vertical space.

  The grid bag layout manager calculates the weight of a row to be the maximum `weighty` of all the components in a row. If the resulting layout is smaller vertically than the area it needs to fill, the extra space is distributed to each row in proportion to its weight. A row that has a weight of zero receives no extra space.

  If all the weights are zero, all the extra space appears between the grids of the cell and the top and bottom edges.

  The default value of this field is `0`. `weighty` should be a non-negative value.

  See Also:
    `GridBagConstraints.clone()`, `GridBagConstraints.weightx`

### anchor

    int anchor

  This field is used when the component is smaller than its display area. It determines where, within the display area, to place the component.

  There are two kinds of possible values: relative and absolute. Relative values are interpreted relative to the container's component orientation property while absolute values are not. The absolute values are: `CENTER`, `NORTH`, `NORTHEAST`, `EAST`, `SOUTHEAST`, `SOUTH`, `SOUTHWEST`, `WEST`, and `NORTHWEST`. The relative values are: `PAGE_START`, `PAGE_END`, `LINE_START`, `LINE_END`, `FIRST_LINE_START`, `FIRST_LINE_END`, `LAST_LINE_START` and `LAST_LINE_END`. The default value is `CENTER`.

  See Also:
    `GridBagConstraints.clone()`, `ComponentOrientation`

### fill

    int fill

  This field is used when the component's display area is larger than the component's requested size. It determines whether to resize the component, and if so, how.

  The following values are valid for `fill`:

  - `NONE`: Do not resize the component.
  - `HORIZONTAL`: Make the component wide enough to fill its display area horizontally, but do not change its height.
  - `VERTICAL`: Make the component tall enough to fill its display area vertically, but do not change its width.

  Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

  Serial Data:
    The `String` is the name of one of `CS_*` constants defined in the `ColorSpace` class if the profile object is a profile for a predefined color space (for example `"CS_sRGB"`). The string is `null` otherwise.

    The `byte[]` array is the profile data for the profile. It will usually be `null` for the predefined profiles.

    If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with `getInstance(int cspace)` and the profile data are ignored. Otherwise the object will be resolved into profile obtained with `getInstance(byte[] data)`.

  Throws:
    `IOException` - thrown by `ObjectInputStream`.

  Serial Data:
    The `String` is the name of one of `CS_*` constants defined in the `ColorSpace` class if the profile object is a profile for a predefined color space (for example `"CS_sRGB"`). The string is `null` otherwise.

    The `byte[]` array is the profile data for the profile. For predefined color spaces `null` is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.

  Throws:

  Deserializes this `DragGestureEvent`. This method first performs default deserialization for all non-`transient` fields. An attempt is then made to deserialize this object's `List` of gesture events as well. This is first attempted by deserializing the field `events`, because, in releases prior to 1.4, a non-`transient` field of this name stored the `List` of gesture events. If this fails, the next object in the stream is used instead. If the resulting `List` is `null`, this object's `List` of gesture events is set to an empty `List`.

  Deserializes this `DragSource`. This method first performs default deserialization. Next, this object's `FlavorMap` is deserialized by using the next object in the stream. If the resulting `FlavorMap` is `null`, this object's `FlavorMap` is set to the default FlavorMap for this thread's `ClassLoader`. Next, this object's listeners are deserialized by reading a `null`-terminated sequence of 0 or more key/value pairs from the stream:
  - If a key object is a `String` equal to `dragSourceListenerK`, a `DragSourceListener` is deserialized using the corresponding value object and added to this `DragSource`.
  - If a key object is a `String` equal to `dragSourceMotionListenerK`, a `DragSourceMotionListener` is deserialized using the corresponding value object and added to this `DragSource`.

                     throws IOException,
                            ClassNotFoundException

  `readObject` for custom serialization.

  This method reads this object's serialized form for this class as follows:

  The `readObject` method is invoked on `in` to read this object's unique identifier (a `UID` instance).

  Next, the `readUTF` method is invoked on `in` to read the external ref type name of the `RemoteRef` instance for this object's activator. Next, the `RemoteRef` instance is created of an implementation-specific class corresponding to the external ref type name (returned by `readUTF`), and the `readExternal` method is invoked on that `RemoteRef` instance to read the external form corresponding to the external ref type name.

  Note: If the external ref type name is `"UnicastRef"`, `"UnicastServerRef"`, `"UnicastRef2"`, `"UnicastServerRef2"`, `"ActivatableRef"`, or `"ActivatableServerRef"`, a corresponding implementation-specific class must be found, and its `readExternal` method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a `ClassNotFoundException` will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case the `RemoteRef` will be an instance of that implementation-specific class.

### writeObject

                      throws IOException,
                             ClassNotFoundException

  `writeObject` for custom serialization.

  This method writes this object's serialized form for this class as follows:

  The `writeObject` method is invoked on `out` passing this object's unique identifier (a `UID` instance) as the argument.

  Next, the `getRefClass` method is invoked on the activator's `RemoteRef` instance to obtain its external ref type name. Next, the `writeUTF` method is invoked on `out` with the value returned by `getRefClass`, and then the `writeExternal` method is invoked on the `RemoteRef` instance passing `out` as the argument.

  Serial Data:
    The serialized data for this class comprises a `java.rmi.server.UID` (written with `ObjectOutput.writeObject`) followed by the external ref type name of the activator's `RemoteRef` instance (a string written with `ObjectOutput.writeUTF`), followed by the external form of the `RemoteRef` instance as written by its `writeExternal` method.

    The external ref type name of the `RemoteRef` instance is determined using the definitions of external ref type names specified in the `RemoteObject` `writeObject` method serialData specification. Similarly, the data written by the `writeExternal` method and read by the `readExternal` method of `RemoteRef` implementation classes corresponding to each of the defined external ref type names is specified in the `RemoteObject` `writeObject` method serialData specification.

  Throws:
    `IOException`

                     throws IOException,
                            ClassNotFoundException

  `readObject` for custom serialization.

  This method reads this object's serialized form for this class as follows:

  The `readUTF` method is invoked on `in` to read the external ref type name for the `RemoteRef` instance to be filled in to this object's `ref` field. If the string returned by `readUTF` has length zero, the `readObject` method is invoked on `in`, and than the value returned by `readObject` is cast to `RemoteRef` and this object's `ref` field is set to that value. Otherwise, this object's `ref` field is set to a `RemoteRef` instance that is created of an implementation-specific class corresponding to the external ref type name returned by `readUTF`, and then the `readExternal` method is invoked on this object's `ref` field.

  If the external ref type name is `"UnicastRef"`, `"UnicastServerRef"`, `"UnicastRef2"`, `"UnicastServerRef2"`, `"ActivatableRef"`, or `"ActivatableServerRef"`, a corresponding implementation-specific class must be found, and its `readExternal` method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a `ClassNotFoundException` will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case this object's `ref` field will be set to an instance of that implementation-specific class.

### writeObject

    private void writeObject(ObjectOutputStream out)
                      throws IOException,
                             ClassNotFoundException

  `writeObject` for custom serialization.

  This method writes this object's serialized form for this class as follows:

  The `getRefClass` method is invoked on this object's `ref` field to obtain its external ref type name. If the value returned by `getRefClass` was a non-`null` string of length greater than zero, the `writeUTF` method is invoked on `out` with the value returned by `getRefClass`, and then the `writeExternal` method is invoked on this object's `ref` field passing `out` as the argument; otherwise, the `writeUTF` method is invoked on `out` with a zero-length string (`""`), and then the `writeObject` method is invoked on `out` passing this object's `ref` field as the argument.

  Serial Data:
    The serialized data for this class comprises a string (written with `ObjectOutput.writeUTF`) that is either the external ref type name of the contained `RemoteRef` instance (the `ref` field) or a zero-length string, followed by either the external form of the `ref` field as written by its `writeExternal` method if the string was of non-zero length, or the serialized form of the `ref` field as written by passing it to the serialization stream's `writeObject` if the string was of zero length.

    If this object is an instance of `java.rmi.server.RemoteStub` that was returned from any of the `UnicastRemoteObject.exportObject` methods and custom socket factories are not used, the external ref type name is `"UnicastRef"`. If this object is an instance of `RemoteStub` that was returned from any of the `UnicastRemoteObject.exportObject` methods and custom socket factories are used, the external ref type name is `"UnicastRef2"`. If this object is an instance of `RemoteStub` that was returned from any of the `java.rmi.activation.Activatable.exportObject` methods, the external ref type name is `"ActivatableRef"`. If this object is an instance of `RemoteStub` that was returned from the `RemoteObject.toStub` method (and the argument passed to `toStub` was not itself a `RemoteStub`), the external ref type name is a function of how the remote object passed to `toStub` was exported, as described above. If this object is an instance of `RemoteStub` that was originally created via deserialization, the external ref type name is the same as that which was read when this object was deserialized.

    If this object is an instance of `java.rmi.server.UnicastRemoteObject` that does not use custom socket factories, the external ref type name is `"UnicastServerRef"`. If this object is an instance of `UnicastRemoteObject` that does use custom socket factories, the external ref type name is `"UnicastServerRef2"`.

    If this object is an instance of `java.rmi.activation.Activatable`, the external ref type name is `"ActivatableServerRef"`.

    Following is the data that must be written by the `writeExternal` method and read by the `readExternal` method of `RemoteRef` implementation classes that correspond to the each of the defined external ref type names:

    For `"UnicastRef"`:

    - the hostname of the referenced remote object, written by `DataOutput.writeUTF(String)`
    - the port of the referenced remote object, written by `DataOutput.writeInt(int)`
    - the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the `ObjID` instance contained in the reference
    - the boolean value `false`, written by `DataOutput.writeBoolean(boolean)`

    For `"UnicastRef2"` with a `null` client socket factory:

    - the byte value `0x00` (indicating `null` client socket factory), written by `DataOutput.writeByte(int)`

  AM and PM strings. For example: "AM" and "PM". An array of 2 strings, indexed by `Calendar.AM` and `Calendar.PM`.

### zoneStrings

    String[][] zoneStrings

  Localized names of time zones in this locale. This is a two-dimensional array of strings of size n by m, where m is at least 5. Each of the n rows is an entry containing the localized names for a single `TimeZone`. Each such row contains (with `i` ranging from 0..n-1):
  - `zoneStrings[i][0]` - time zone ID
  - `zoneStrings[i][1]` - long name of zone in standard time
  - `zoneStrings[i][2]` - short name of zone in standard time
  - `zoneStrings[i][3]` - long name of zone in daylight savings time
  - `zoneStrings[i][4]` - short name of zone in daylight savings time
  The zone ID is not localized; it corresponds to the ID value associated with a system time zone object. All other entries are localized names. If a zone does not implement daylight savings time, the daylight savings time names are ignored.

  See Also:
    `TimeZone`

### localPatternChars

    String localPatternChars

  Localized date-time pattern characters. For example, a locale may wish to use 'u' rather than 'y' to represent years in its date format pattern strings. This string must be exactly 18 characters long, with the index of the characters described by `DateFormat.ERA_FIELD`, `DateFormat.YEAR_FIELD`, etc. Thus, if the string were "Xz...", then localized patterns would use 'X' for era and 'z' for year.

                     throws IOException,
                            ClassNotFoundException

  First, read the default serializable fields from the stream. Then if `serialVersionOnStream` is less than 1, indicating that the stream was written by JDK 1.1, initialize `useExponentialNotation` to false, since it was not present in JDK 1.1. Finally, set serialVersionOnStream back to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

  If the minimum or maximum integer digit count is larger than `DOUBLE_INTEGER_DIGITS` or if the minimum or maximum fraction digit count is larger than `DOUBLE_FRACTION_DIGITS`, then the stream data is invalid and this method throws an `InvalidObjectException`.

  Stream versions older than 2 will not have the affix pattern variables `posPrefixPattern` etc. As a result, they will be initialized to `null`, which means the affix strings will be taken as literal values. This is exactly what we want, since that corresponds to the pre-version-2 behavior.

Serialized Fields

### positivePrefix

    String positivePrefix

  The symbol used as a prefix when formatting positive numbers, e.g. "+".

  See Also:

### negativeSuffix

    String negativeSuffix

  The symbol used as a suffix when formatting negative numbers. This is often an empty string.

  See Also:

### posPrefixPattern

    String posPrefixPattern

  The prefix pattern for non-negative numbers. This variable corresponds to `positivePrefix`.

  This pattern is expanded by the method `expandAffix()` to `positivePrefix` to update the latter to reflect changes in `symbols`. If this variable is `null` then `positivePrefix` is taken as a literal value that does not change when `symbols` changes. This variable is always `null` for `DecimalFormat` objects older than stream version 2 restored from stream.

  Since:
    1.3

### posSuffixPattern

    String posSuffixPattern

  The suffix pattern for non-negative numbers. This variable corresponds to `positiveSuffix`. This variable is analogous to `posPrefixPattern`; see that variable for further documentation.

  Reads the default serializable fields, provides default values for objects in older serial versions, and initializes non-serializable fields. If `serialVersionOnStream` is less than 1, initializes `monetarySeparator` to be the same as `decimalSeparator` and `exponential` to be 'E'. If `serialVersionOnStream` is less then 2, initializes `locale`to the root locale. Sets `serialVersionOnStream` back to the maximum allowed value so that default serialization will work properly if this object is streamed out again. Initializes the currency from the intlCurrencySymbol field.

  First, read in the default serializable data. Then, if `serialVersionOnStream` is less than 1, indicating that the stream was written by JDK 1.1, set the `int` fields such as `maximumIntegerDigits` to be equal to the `byte` fields such as `maxIntegerDigits`, since the `int` fields were not present in JDK 1.1. Finally, set serialVersionOnStream back to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

  If `minimumIntegerDigits` is greater than `maximumIntegerDigits` or `minimumFractionDigits` is greater than `maximumFractionDigits`, then the stream data is invalid and this method throws an `InvalidObjectException`. In addition, if any of these values is negative, then this method throws an `InvalidObjectException`.

  Reconstitute this object from a stream (i.e., deserialize it).

### writeObject

    private void writeObject(ObjectOutputStream stream)
                      throws IOException

  Save the state of this object to a stream (i.e., serialize it). Ideally, `Calendar` would only write out its state data and the current time, and not write any field data out, such as `fields[]`, `isTimeSet`, `areFieldsSet`, and `isSet[]`. `nextStamp` also should not be part of the persistent state. Unfortunately, this didn't happen before JDK 1.1 shipped. To be compatible with JDK 1.1, we will always have to write out the field values and state flags. However, `nextStamp` can be removed from the serialization stream; this will probably happen in the near future.

Serialized Fields

### fields

    int[] fields

  The field values for the currently set time for this calendar. This is an array of `FIELD_COUNT` integers, with index values `ERA` through `DST_OFFSET`.

### isSet

    boolean[] isSet

  The flags which tell if a specified time field for the calendar is set. A new object has no fields set. After the first call to a method which generates the fields, they all remain set after that. This is an array of `FIELD_COUNT` booleans, with index values `ERA` through `DST_OFFSET`.

### time

    long time

  The currently set time for this calendar, expressed in milliseconds after January 1, 1970, 0:00:00 GMT.

  See Also:
    `Calendar.isTimeSet`

### isTimeSet

    boolean isTimeSet

  True if then the value of `time` is valid. The time is made invalid by a change to an item of `field[]`.

  See Also:
    `Calendar.time`

### areFieldsSet

    boolean areFieldsSet

  True if `fields[]` are in sync with the currently set time. If false, then the next attempt to get the value of a field will force a recomputation of all fields from the current value of `time`.

### lenient

    boolean lenient

  True if this calendar allows out-of-range field values during computation of `time` from `fields[]`.

  See Also:
    `Calendar.setLenient(boolean)`

### zone

    TimeZone zone

  The `TimeZone` used by this calendar. Calendar uses the time zone data to translate between locale and GMT time.

### firstDayOfWeek

    int firstDayOfWeek

  The first day of the week, with possible values `SUNDAY`, `MONDAY`, etc. This is a locale-dependent value.

### minimalDaysInFirstWeek

    int minimalDaysInFirstWeek

  The number of days required for the first week in a month or year, with possible values from 1 to 7. This is a locale-dependent value.

### nextStamp

    int nextStamp

  The next available value for `stamp[]`, an internal array. This actually should not be written out to the stream, and will probably be removed from the stream in the near future. In the meantime, a value of `MINIMUM_USER_STAMP` should be used.

### serialVersionOnStream

    int serialVersionOnStream

  The version of the serialized data on the stream. Possible values:
  0 or not present on stream
    JDK 1.1.5 or earlier.
  1
    JDK 1.1.6 or later. Writes a correct 'time' value as well as compatible values for other fields. This is a transitional format.
  When streaming out this class, the most recent format and the highest allowable `serialVersionOnStream` is written.

                            ClassNotFoundException

  Reconstitute this object from a stream (i.e., deserialize it). We handle both JDK 1.1 binary formats and full formats with a packed byte array.

### writeObject

    private void writeObject(ObjectOutputStream stream)
                      throws IOException

  Save the state of this object to a stream (i.e., serialize it).

  Serial Data:
    We write out two formats, a JDK 1.1 compatible format, using `DOW_IN_MONTH_MODE` rules, in the required section, followed by the full rules, in packed format, in the optional section. The optional section will be ignored by JDK 1.1 code upon stream in.

    Contents of the optional section: The length of a byte array is emitted (int); this is 4 as of this release. The byte array of the given length is emitted. The contents of the byte array are the true values of the fields `startDay`, `startDayOfWeek`, `endDay`, and `endDayOfWeek`. The values of these fields in the required section are approximate values suited to the rule mode `DOW_IN_MONTH_MODE`, which is the only mode recognized by JDK 1.1.

  Throws:

Serialized Fields

### startMonth

    int startMonth

  The month in which daylight saving time starts. This value must be between `Calendar.JANUARY` and `Calendar.DECEMBER` inclusive. This value must not equal `endMonth`.

  If `useDaylight` is false, this value is ignored.

### startDay

    int startDay

  This field has two possible interpretations:
  `startMode == DOW_IN_MONTH`
    `startDay` indicates the day of the month of `startMonth` on which daylight saving time starts, from 1 to 28, 30, or 31, depending on the `startMonth`.
  `startMode != DOW_IN_MONTH`
    `startDay` indicates which `startDayOfWeek` in th month `startMonth` daylight saving time starts on. For example, a value of +1 and a `startDayOfWeek` of `Calendar.SUNDAY` indicates the first Sunday of `startMonth`. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

  If `useDaylight` is false, this value is ignored.

  ### startDayOfWeek

      int startDayOfWeek

    The day of the week on which daylight saving time starts. This value must be between `Calendar.SUNDAY` and `Calendar.SATURDAY` inclusive.

    If `useDaylight` is false or `startMode == DAY_OF_MONTH`, this value is ignored.

  ### startTime

      int startTime

    The time in milliseconds after midnight at which daylight saving time starts. This value is expressed as wall time, standard time, or UTC time, depending on the setting of `startTimeMode`.

    If `useDaylight` is false, this value is ignored.

  ### startTimeMode

      int startTimeMode

    The format of startTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.

    Since:
      1.3

  ### endMonth

      int endMonth

    The month in which daylight saving time ends. This value must be between `Calendar.JANUARY` and `Calendar.UNDECIMBER`. This value must not equal `startMonth`.

    If `useDaylight` is false, this value is ignored.

  ### endDay

      int endDay

    This field has two possible interpretations:
    `endMode == DOW_IN_MONTH`
      `endDay` indicates the day of the month of `endMonth` on which daylight saving time ends, from 1 to 28, 30, or 31, depending on the `endMonth`.
    `endMode != DOW_IN_MONTH`
      `endDay` indicates which `endDayOfWeek` in th month `endMonth` daylight saving time ends on. For example, a value of +1 and a `endDayOfWeek` of `Calendar.SUNDAY` indicates the first Sunday of `endMonth`. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

    If `useDaylight` is false, this value is ignored.

    ### endDayOfWeek

        int endDayOfWeek

      The day of the week on which daylight saving time ends. This value must be between `Calendar.SUNDAY` and `Calendar.SATURDAY` inclusive.

      If `useDaylight` is false or `endMode == DAY_OF_MONTH`, this value is ignored.

    ### endTime

        int endTime

      The time in milliseconds after midnight at which daylight saving time ends. This value is expressed as wall time, standard time, or UTC time, depending on the setting of `endTimeMode`.

      If `useDaylight` is false, this value is ignored.

    ### endTimeMode

        int endTimeMode

      The format of endTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.

      Since:
        1.3

    ### startYear

        int startYear

      The year in which daylight saving time is first observed. This is an AD value. If this value is less than 1 then daylight saving time is observed for all AD years.

      If `useDaylight` is false, this value is ignored.

    ### rawOffset

        int rawOffset

      The offset in milliseconds between this zone and GMT. Negative offsets are to the west of Greenwich. To obtain local standard time, add the offset to GMT time. To obtain local wall time it may also be necessary to add `dstSavings`.

    ### useDaylight

        boolean useDaylight

      A boolean value which is true if and only if this zone uses daylight saving time. If this value is false, several other fields are ignored.

    ### monthLength

        byte[] monthLength

      This field was serialized in JDK 1.1, so we have to keep it that way to maintain serialization compatibility. However, there's no need to recreate the array each time we create a new time zone.

      An array of bytes containing the values {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}. This is ignored as of the Java 2 platform v1.2, however, it must be streamed out for compatibility with JDK 1.1.

    ### startMode

        int startMode

      Variables specifying the mode of the start rule. Takes the following values:
      `DOM_MODE`
        Exact day of week; e.g., March 1.

        Day of week in month; e.g., last Sunday in March.
      `DOW_GE_DOM_MODE`
        Day of week after day of month; e.g., Sunday on or after March 15.
      `DOW_LE_DOM_MODE`
        Day of week before day of month; e.g., Sunday on or before March 15.
      The setting of this field affects the interpretation of the `startDay` field.

      If `useDaylight` is false, this value is ignored.

      Since:
        1.1.4

    ### endMode

        int endMode

      Variables specifying the mode of the end rule. Takes the following values:

      `DOW_LE_DOM_MODE`
        Day of week before day of month; e.g., Sunday on or before March 15.
      The setting of this field affects the interpretation of the `endDay` field.

      If `useDaylight` is false, this value is ignored.

      Since:
        1.1.4

    ### dstSavings
