III Problem 2: *13.5 (Enable GeometricObject comparable) Modify the GeometricObject class to implement the Comparable interface, and define a static max method in the GeometricObject class for finding the larger of two GeometricObject objects. Implement the new GeometricObject class. Write a test program that uses the max method to find the larger of two circles and the larger of two rectangles. Instructions: Given the following "main" method, complete the "exam4p2.java" so that the following output will be produced: 1. The "main" program: public class exam4p2 // Main method public static void main(Stringl args) // Create two comparable circles Circle1 circle1 new Circle1(5); Circle1 circle2- new Circle1(4); // Display the max circle Circle1 circle (Circle1) GeometricObject1.max(circle1,circle2); System.out.println("The max circle's radius is " +circle.getRadius() System.out.println(circle); Circle1) Geometricobject1.max(circle1, circle2); 2. The output of the complete program: The max circle's radius is 5.0 [Circle] radius = 5.0
