Design a class named Point that meets the following requirements:

■ Two data fields x and y for representing a point with getter methods

■ A no-arg constructor that constructs a point for (0, 0)

■ A constructor that constructs a point with the specified x and y values

■ Override the equals method. Point p1 is said to be equal to point p2 if p1.x = = p2.x and p1.y = = p2.y.

■ Override the hashCode method. (For reference, see the implementation of the Point2D class in the Java API.)
