From Textbook page 424 use Listing 11.6 DynamicBindingDemo.java Add a class that extends Object and a class that extends the new class you just created. Add the code to create objects from the new classes you created which will print what each class is. These new classes can be animal, vegetable or mineral, in other words just two classes that it makes sense for the second class created to extend from the first class extend. Please help.

Solution

public class DynamicBindingDemo {
   public static void main(String[] args) {
       m(new GraduateStudent());
       m(new Student());
       m(new Person());
       m(new Object());
       // method invocation
       m(new Animal());
       m(new HerbivorousAnimal());
       }

       public static void m(Object x) {
       System.out.println(x.toString());
       }
}
class GraduateStudent extends Student {
}

class Student extends Person {
@Override
public String toString() {
return \"Student\";
}
}

class Person extends Object {
@Override
public String toString() {
return \"Person\";
}
}

class Animal extends Object{
   @Override
   public String toString() {
       return \"Animal\";
   }
}

// HerbivorousAnimal class extends Animal
class HerbivorousAnimal extends Animal{
   @Override
   public String toString() {
       return \"HerbivorousAnimal\";
   }
}
