Question

The files at the links below contain source code for three interrelated classes, a Dog class, a DogOwner class, and a DogTester class that manipulates objects from the other two classes. DogTester.java DogOwner.java Dog.java Lancelot (formerly Chuckles) is an 8 kg spaniel who isn't a show dog. Lancelot starts to gain weight. Its weight goes up by 2 kg. Change Lancelot's weight accordingly in the main method in the DogTester class: public class DogTester { public static void main (String[] arg) { DogOwner jill; Dog d = new Dog("Hotdog", "poodle", 15.0, true); jill = new DogOwner("Jill", d); Dog c = new Dog("Chuckles", "spaniel", 8.0, false); jill.setDog(c); jill.setName("Darth"); jill.getDog().setName("Lancelot");
