Class Point

java.lang.Object
  com.sun.dtv.lwuit.geom.Point

public class Point
extends Object

A point representing a location in (x, y) coordinate space, specified in integer precision.

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

Object	clone() Creates a new object of the same class and with the same contents as this object.
boolean	equals(Object obj) Determines whether or not two points are equal.
Point	getLocation() Returns the location of this point.
int	getX() Returns the x coordinate of this Point.
int	getY() Returns the y coordinate of this Point.
int	hashCode() Returns the hashcode for this Point.
void	move(int x, int y) Moves this point to the specified location in the (x, y) coordinate plane.
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).
