Point2D.Double, Point2D.Float |
| Field Summary | |
|---|---|
int |
x
The x coordinate. |
int |
y
The y coordinate. |
| Constructor Summary | |
|---|---|
Point()
Constructs and initializes a point at the origin (0, 0) of the coordinate space. |
|
Point(int x,
int y)
Constructs and initializes a point at the specified (x, y) location in the coordinate space. |
|
Point(Point p)
Constructs and initializes a point with the same location as the specified Point object. |
|
| Method Summary | |
|---|---|
boolean |
equals(Object obj)
Determines whether or not two points are equal. |
Point |
getLocation()
Returns the location of this point. |
double |
getX()
Returns the X coordinate of the point in double precision. |
double |
getY()
Returns the Y coordinate of the point in double precision. |
void |
move(int x,
int y)
Moves this point to the specified location in the (x, y) coordinate plane. |
void |
setLocation(double x,
double y)
Sets the location of this point to the specified double coordinates. |
void |
setLocation(int x,
int y)
Changes the point to have the specified location. |
void |
setLocation(Point p)
Sets the location of the point to the specified location. |
String |
toString()
Returns a string representation of this point and its location in the (x, y) coordinate space. |
void |
translate(int dx,
int dy)
Translates this point, at location (x, y), by dx along the x axis and dy
along the y axis so that it now represents the point
(x + dx,
y + dy). |

public double getX()
getX in class Point2Dpublic double getY()
getY in class Point2Dpublic Point getLocation()
getLocation method of Component.
Component.getLocation(),
setLocation(java.awt.Point),
setLocation(int, int)public void setLocation(Point p)
setLocation method of Component.
p - a point, the new location for this pointComponent.setLocation(java.awt.Point),
getLocation()
public void setLocation(int x,
int y)
This method is included for completeness, to parallel the
setLocation method of Component.
Its behavior is identical with move(int, int).
x - the x coordinate of the new locationy - the y coordinate of the new locationComponent.setLocation(int, int),
getLocation(),
move(int, int)
public void setLocation(double x,
double y)
Integer.MIN_VALUE
will be reset to MIN_VALUE, and any number
larger than Integer.MAX_VALUE will be
reset to MAX_VALUE.
setLocation in class Point2Dx - the x coordinate of the new locationy - the y coordinate of the new locationgetLocation()
public void move(int x,
int y)
setLocation(int, int).
x - the x coordinate of the new locationy - the y coordinate of the new locationComponent.setLocation(int, int)
public void translate(int dx,
int dy)
dx along the x axis and dy
along the y axis so that it now represents the point
(x + dx,
y + dy).
dx - the distance to move this point
along the x axisdy - the distance to move this point
along the y axispublic boolean equals(Object obj)
Point2D are equal if the values of their
x and y member fields, representing
their position in the coordinate space, are the same.
equals in class Point2Dobj - an object to be compared with this Point2D
true if the object to be compared is
an instance of Point2D and has
the same values; false otherwise.Object.hashCode(),
Hashtablepublic String toString()
null.
