Point

• java.lang.Object
  • java.awt.geom.Point2D

Fields Summary
public int	x The x coordinate. If no x coordinate is set it will default to 0.
public int	y The y coordinate. If no y coordinate is set it will default to 0.
private static final long	serialVersionUID

Constructors Summary
public Point() Constructs and initializes a point at the origin (0, 0) of the coordinate space. since JDK1.1 this(0, 0);
public Point(Point p) Constructs and initializes a point with the same location as the specified Point object. param p a point since JDK1.1 this(p.x, p.y);
public Point(int x, int y) Constructs and initializes a point at the specified (x, y) location in the coordinate space. param x the x coordinate param y the y coordinate this.x = x; this.y = y;

Methods Summary
public boolean	equals(java.lang.Object obj) Determines whether or not two points are equal. Two instances of Point2D are equal if the values of their x and y member fields, representing their position in the coordinate space, are the same. param obj an object to be compared with this Point2D return true if the object to be compared is an instance of Point2D and has the same values; false otherwise. if (obj instanceof Point) { Point pt = (Point)obj; return (x == pt.x) && (y == pt.y); } return super.equals(obj);
public java.awt.Point	getLocation() Returns the location of this point. This method is included for completeness, to parallel the getLocation method of Component. return a copy of this point, at the same location see java.awt.Component#getLocation see java.awt.Point#setLocation(java.awt.Point) see java.awt.Point#setLocation(int, int) since JDK1.1 return new Point(x, y);
public double	getX() Returns the X coordinate of the point in double precision. return the X coordinate of the point in double precision return x;
public double	getY() Returns the Y coordinate of the point in double precision. return the Y coordinate of the point in double precision return y;
public void	move(int x, int y) Moves this point to the specified location in the (x, y) coordinate plane. This method is identical with setLocation(int, int). param x the x coordinate of the new location param y the y coordinate of the new location see java.awt.Component#setLocation(int, int) this.x = x; this.y = y;
public void	setLocation(java.awt.Point p) Sets the location of the point to the specified location. This method is included for completeness, to parallel the setLocation method of Component. param p a point, the new location for this point see java.awt.Component#setLocation(java.awt.Point) see java.awt.Point#getLocation since JDK1.1 setLocation(p.x, p.y);
public void	setLocation(int x, int y) Changes the point to have the specified location. This method is included for completeness, to parallel the setLocation method of Component. Its behavior is identical with move(int, int). param x the x coordinate of the new location param y the y coordinate of the new location see java.awt.Component#setLocation(int, int) see java.awt.Point#getLocation see java.awt.Point#move(int, int) since JDK1.1 move(x, y);
public void	setLocation(double x, double y) Sets the location of this point to the specified double coordinates. The double values will be rounded to integer values. Any number smaller than Integer.MIN_VALUE will be reset to MIN_VALUE, and any number larger than Integer.MAX_VALUE will be reset to MAX_VALUE. param x the x coordinate of the new location param y the y coordinate of the new location see #getLocation this.x = (int) Math.floor(x+0.5); this.y = (int) Math.floor(y+0.5);
public java.lang.String	toString() Returns a string representation of this point and its location in the (x, y) coordinate space. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null. return a string representation of this point return getClass().getName() + "[x=" + x + ",y=" + y + "]";
public 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). param dx the distance to move this point along the x axis param dy the distance to move this point along the y axis this.x += dx; this.y += dy;
