What's wrong with this example of Java property inheritance?

Question

Inheritance.java

public class InheritanceExample {
  static public void main(String[] args){
    Cat c = new Cat();
    System.out.println(c.speak());

            


        

Answer 1

You're hiding fields. The sound in Animal is not the same String as the sound in Cat.

One possible solution is to create a constructor and there simply say

super.sound = "meow";

instead of in the class body saying

protected String sound = "meow";

to set the field.
