Chapter 27, Problem 27.14PE

(The Point class) 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.)
