Method overriding

Declaring a method in subclass which is already present in parent class is known as method overriding.

Examples:

class Animal

{

      public void move()

      {
             System.out.println("Animals can move");
      }
}

 

class Dog extends Animal

{

     public void move()

      {
            System.out.println("Dogs can walk and run");
      }
}

 

class MethodOverridingDemo

{

      public static void main(String args[])

      {
              Animal aObj1 = new Animal(); 

              Dog dObj = new Dog();

              Animal aObj2 = new Dog(); 

             

              aObj1.move();

              dObj.move();

              aObj2.move();         // Dynamic method dispatch

       }
}

 

Output

Animals can move

Dogs can walk and run

Dogs can walk and run
