1. Create a Geometric object list that has combination of Circle and Rectangle object.

2. User Collection object utility to sort that list based on GeometricObjectComparator class attached.

3. Just submit your project6.java.

TestComparator.java GeometricObjectComparator.java Circle.java GeometricObject.java Rectangle.java

public class TestComparator { public static void main(String[] args) { GeometricObject g1 = new Rectangle(5, 5); GeometricObject g2 = new Circle(5);
