jdk.awt.geom.Point2D
The Point2D class defines a point representing a location in (x,y) coordinate space.
This class is only the abstract superclass for all objects that store a 2D coordinate. The actual storage representation of the coordinates is left to the subclass.

(clone this)Creates a new object of the same class and with the same contents as this object.
returns: a clone of this instance. - java.lang.Object
throws: java.lang.OutOfMemoryError - if there is not enough memory.

equalsclj
(equals this 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.
obj - an object to be compared with this Point2D - java.lang.Object
returns: true if the object to be compared is
an instance of Point2D and has
the same values; false otherwise. - boolean
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.
obj - an object to be compared with this Point2D - `java.lang.Object`
returns: true if the object to be compared is
an instance of Point2D and has
the same values; false otherwise. - `boolean`get-xclj
(get-x this)Returns the X coordinate of this Point2D in double precision.

get-yclj
(get-y this)Returns the Y coordinate of this Point2D in double precision.
returns: the Y coordinate of this Point2D. - double
Returns the Y coordinate of this Point2D in double precision. returns: the Y coordinate of this Point2D. - `double`
hash-codeclj
(hash-code this)Returns the hashcode for this Point2D.
