Write the class definition for a circle that has one instance variable for the radius.This class must have 2 constructors(one is the default,and the other has one argument).Also define appropriate get-and set-methods,as well as methods to return the diameter, circumference, and area of a circle.Use the math class for calculations where possible.

Write another class that contains a main method in which you use both constructors to construct 2 circle objects.Use the Joptionpane class to get the radius values for each of the objects.

Call the appropriate methods to display the radius, diameter, circumference and area of each of the objects.

Use the Joptionpane class to display the values.
