5. Given the Java Point class (which contains two private variables x and y and constructors that allows creating a point object with known x and y values as well as other methods such as equals( ), toString( ) etc), (a). define a new class called Circle that contains private two variables: center which is a Point object from the Point class and radius which is of type double. The Circle class must have the following methods: (b). add a constructor which creates a circle object using a center point with x and y values and a radius as its parameters. (c). add a default constructor. ( (d). add an equals() method that can compare if any object is equal to a Circle object (two circle objects are equal if they have the same center point with the same radius). (e). add a toString() method that prints a Circle object with the center point and radius.
