Class java.awt.geom.Point2D

java.lang.Object
    |
    +----java.awt.geom.Point2D

public abstract class Point2D

extends Object

This class is only the abstract superclass for all objects which store a 2D coordinate. The actual storage representation of the coordinates is left to the subclass.

Point2D.Double

A point specified in double precision.

Point2D.Float

A point specified in float precision.

Point2D()

equals(Object)

Determines whether two points are equal.

getX()

Returns the X coordinate of the point in double precision.

getY()

Returns the Y coordinate of the point in double precision.

setLocation(double, double)

Sets the location of this point to the specified float coordinates.

setLocation(Point2D)

Sets the location of this point to the same coordinates as the specified Point object.

protected Point2D()

public abstract double getX()

Returns the X coordinate of the point in double precision.

public abstract double getY()

Returns the Y coordinate of the point in double precision.

public abstract void setLocation(double x,
                                 double y)

Sets the location of this point to the specified float coordinates.

public void setLocation(Point2D p)

Sets the location of this point to the same coordinates as the specified Point object.

public boolean equals(Object obj)

Determines whether 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.

Parameters:

obj - an object to be compared with this point.

Returns:

true if the object to be compared is an instance of Point2D and has the same values; false otherwise.

Overrides:

equals in class Object
