The program must: GeometricObject classes: -It should be an abstract class, so that no instances can be made of it. -It must define three abstract methods, boolean equals (Object other), double getArea () and double getPerimeter (). These must be implemented by the child classes. -It must implement Comparable interface and associated int compareTo () method. Comparable is an interface defined in the Java library, you should not write your own Comparable interface. -Area is used for comparison of geometric objects, the object with the largest area is assumed to be the largest by comparison. -The class must have a static GeometricObject max (GeometricObject obj1, GeometricObject obj2) method that returns the largest object. Tip: Use the compareTo method when comparing obj1 and obj2. Test class: -It will create two objects of each class with different sizes. -It should use the max method in GeometricObject to find the largest object of each type and print info about each of them. - -It should find the largest object of the three largest objects found in the point above. For the GeometricObject, Triangle, Rectangle and Circle classes see the attached UML diagrams.
