public boolean equals (Object obj)

Determines whether or not two points are equal.

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.
Returns: true if the object to be compared is an instance of Point2D and has the same values; false otherwise.
Parameters:
- obj - an object to be compared with this Point2D
Since: 1.2
