java.lang.Short
public final class Short
The Short class wraps a value of primitive type
short in an object. An object of type
Short contains a single field whose type is
short.
In addition, this class provides several methods for converting a
short to a String and a
String to a short, as well as other
constants and methods useful when dealing with a short.

have, 215-1. |

public Short(short value)
Short object that

value - the value to be represented by the
Short.
public Short(String s)
throws NumberFormatException
Short object that
represents the short value indicated by the
String parameter. The string is converted to a
short value in exactly the manner used by the
parseShort method for radix 10.
s - the String to be converted to a
Short
NumberFormatException - If the String
does not contain a parsable short.parseShort(java.lang.String, int)| Method Detail |

public static String toString(short s)
String object representing the
specified short. The radix is assumed to be 10.
s - the short to be converted
shortInteger.toString(int)
public static short parseShort(String s)
throws NumberFormatException
short. The characters in the string must all be
decimal digits, except that the first character may be an ASCII
minus sign '-' ('\u002D') to
indicate a negative value. The resulting short value is
returned, exactly as if the argument and the radix 10 were
given as arguments to the parseShort(java.lang.String,
int) method.
s - a String containing the short
representation to be parsed
short value represented by the
argument in decimal.
NumberFormatException - If the string does not
contain a parsable short.
public static short parseShort(String s,
int radix)
throws NumberFormatException
short in
the radix specified by the second argument. The characters in
the string must all be digits, of the specified radix (as
determined by whether Character.digit(char,
int) returns a nonnegative value) except that the first
character may be an ASCII minus sign '-'
('\u002D') to indicate a negative value. The
resulting byte value is returned.
An exception of type NumberFormatException is
thrown if any of the following situations occurs:
null or is a string of
length zero.
Character.MIN_RADIX or larger than Character.MAX_RADIX.
'-' ('\u002D') provided that the
string is longer than length 1.
short.
s - the String containing the
short representation to be parsedradix - the radix to be used while parsing s
short represented by the string
argument in the specified radix.
NumberFormatException - If the String
does not contain a parsable short.
public static Short valueOf(String s,
int radix)
throws NumberFormatException
Short object holding the value
extracted from the specified String when parsed
with the radix given by the second argument. The first argument
is interpreted as representing a signed short in
the radix specified by the second argument, exactly as if the
argument were given to the parseShort(java.lang.String,
int) method. The result is a Short object that
represents the short value specified by the string.
In other words, this method returns a Short object
equal to the value of:
new Short(Short.parseShort(s, radix))
s - the string to be parsedradix - the radix to be used in interpreting s
Short object holding the value
represented by the string argument in the
specified radix.
NumberFormatException - If the String does
not contain a parsable short.
public static Short valueOf(String s)
throws NumberFormatException
Short object holding the
value given by the specified String. The argument
is interpreted as representing a signed decimal
short, exactly as if the argument were given to
the parseShort(java.lang.String) method. The result is
a Short object that represents the
short value specified by the string. In other
words, this method returns a Byte object equal to
the value of:
new Short(Short.parseShort(s))
s - the string to be parsed
Short object holding the value
represented by the string argument
NumberFormatException - If the String does
not contain a parsable short.public static Short valueOf(short s)
Short(short), as this method is likely to yield
significantly better space and time performance by caching
frequently requested values.
s - a short value.
public static Short decode(String nm)
throws NumberFormatException
String into a Short.
Accepts decimal, hexadecimal, and octal numbers given by
the following grammar:
DecimalNumeral, HexDigits, and OctalDigits are defined in §3.10.1 of the Java Language Specification.
- DecodableString:
- Signopt DecimalNumeral

0xHexDigits- Signopt
0XHexDigits- Signopt
#HexDigits- Signopt

- Sign:
-
The sequence of characters following an (optional) negative
sign and/or radix specifier ("0x",
"0X", "#", or
leading zero) is parsed as by the Short.parseShort
method with the indicated radix (10, 16, or 8). This sequence
of characters must represent a positive value or a NumberFormatException will be thrown. The result is negated
if first character of the specified String is the
minus sign. No whitespace characters are permitted in the
String.
nm - the String to decode.
