Implement the Point and Circle classes that are outlined below.

Implement each class method according to the method's given Javadoc comment.

You do not need to write any code that calls your methods. Your methods will be called and tested by the Tester.java program. The Tester.java program expects a single input integer between $1$ and $3.$ The Tester.java program then runs one of its three built in test cases.$/**$

This class represents points in the plane.
