Enable GeometricObject comparable Modify the GeometricObject

(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. Write a test program that uses the max method to find the larger of two circles and the larger of two rectangles.

Solution

package Geometric;

import ToolKit.Circle2D;

import ToolKit.GeometricObject;

import ToolKit.MyRectangle2D;

public class Exercise_05 {

public static void main(String[] args) {

Circle2D c1 = new Circle2D(0, 0, 5);

Circle2D c2 = new Circle2D(0, 0, 2);

Circle2D maxCircle =(Circle2D)GeometricObject.max(c1, c2);

System.out.println(\"Circle 1: \" + c1);

System.out.println(\"Circle 2: \" + c2);

System.out.println(\"Max circle is: \" + maxCircle);

MyRectangle2D r1 = new MyRectangle2D(0, 0, 10, 5);

MyRectangle2D r2 = new MyRectangle2D(0, 0, 10, 10);

MyRectangle2D maxRectangle = (MyRectangle2D) GeometricObject.max(r1, r2);

System.out.println(\"MyRec2 1: \" + r1);

System.out.println(\"MyRec2 2: \" + r2);

System.out.println(\"Max MyRec2 is: \" + maxRectangle);

}
