Java Generic method overriding in a generic class.

// Overriding a generic method in a generic class. 
class MyClass<T> {  
  T ob; // declare an object of type T  
    /* w  ww.  j av a 2  s.  co  m*/
  // Pass the constructor a reference to   
  // an object of type T.  
  public MyClass(T o) {  
    ob = o;  
  }  
  
  // Return ob.  
  public T getob() {  
    System.out.print("Gen's getob(): " ); 
    return ob;  
  }  
}

  MySubclass(T o) { 
    super(o);

  // Override getob(). 
  public T getob() {  
    System.out.print("MySubclass's getob(): "); 
    return ob;  
  }

// Demonstrate generic method override.
