S5P2

WAP that illustrates method overriding. Class A3 is extended by Class B3. Each of these classes defines a hello(string s) method that outputs the string “A3: Hello From -” or “B3: Hello From -” respectively. Use the concept Dynamic Method Dispatch and keyword super.


Code:

 class A3  
 {  
      String S;  
      A3(String s)  
      {  
           hello(s);  
      }  
      public void hello(String s)  
      {  
           S = s;  
           System.out.println("A3 : Hello From "+S);  
      }  
 }  
 class B3 extends A3  
 {  
      B3(String s)  
      {  
           super(s);  
      }  
      public void hello(String s)  
      {  
           S = s;  
           System.out.println("B3 : Hello From "+S);  
      }  
 }  
 class S5P2_Override  
 {  
      public static void main(String args[])  
      {  
           A3 a = new A3("DD");  
           A3 b = new B3("DD");  
      }  
 }  

Output:
