In this second exercise, we are going to look at the impact of overriding the equals and toString methods. Start by copying over your TestEquals class from the previous exercise. You will not need to make any changes to this code.(Already have copied over) Instead, you are going to add the following methods to your Ball class: public String toString() public boolean equals(Ball other) ===================================== public class TestEquals { public static void main(String[] args) { System.out.println(“** Object **”); Object obj1 = new Object(); Object obj2 = new Object(); Object obj3 = obj1; // Print out all three objects System.out.println(obj1); System.out.println(obj2); System.out.println(obj3); // Print a true statement using 2 objects and == System.out.println(obj1==obj3); // Print a false statement using 2 objects and == System.out.println(obj1==obj2); // Print a true statement using 2 objects and .equals() System.out.println(obj1.equals(obj3)); // Print a false statement using 2 objects and .equals() System.out.println(obj1.equals(obj2)); System.out.println(“** Ball **”); Ball ball1 = new Ball(“Red”); Ball ball2 = new Ball(“Red”); Ball ball3 = ball1; // Print out all three objects System.out.println(ball1); System.out.println(ball2); System.out.println(ball3); // Print a true statement using 2 objects and == System.out.println(ball1==ball3); // Print a false statement using 2 objects and == System.out.println(ball1==ball2); // Print a true statement using 2 objects and .equals() System.out.println(ball1.equals(ball3)); // Print a false statement using 2 objects and .equals() System.out.println(ball1.equals(ball2)); } } ===================================== public class Ball { private String color; public Ball(String color){ this.color = color; } public String getColor(){ return color; } // Write an equals method here that returns true if // the colors are the same. // Write a toString statement here, for example: // Color: Red }
