Suppose in the hierarchy of animal classes (see Fig 1) you forget to define the Zebra class. Now you have to add it after all the classes are created. How can you create the Zebra class in the best possible way to avoid redundancy and what do you think is the worst case of the Zebra class creation? (Hint: Zebra is similar to Horse in characteristics )

If the structure of the Animal and the Horse class is given as:

public class Animal {

public void eat() {

System.out.println (grass or meat);

}

}

public class Horse extends Animal {

public void eat() {

System.out.println("Eats grass");

}

public void speak(){

System.out.println("Neigh");}

}

Write the code to add the Zebra class.
