Let us consider two classes class Animal, a more generic class and class Cat, a more specific class i.e a more specific animal. Let us settle for simple definitions for both the classes so as to get the concept right.
/*
The definition for more generic class Animal
Notice the eat() method, which will be inherited by all Classes extending Animal
*/
class Animal
{
public void eat()
{
System.out.println(“Animal Eating“);
}
}
