  ya we can 😀 But you need to assign the base class instance to child class instance.

  Can you please explain more ?

  What is the real purpose of doing so?
  
  PS: google it. you can find it

  Yes you can by overloading concept..
  Check this code...
  

  class k
  {
  public void show(int x)
  {
  System.out.println("mohit kumar singh ");
  }
  }
  public class p extends k
  {
  public void show()
  {
  System.out.println("mohit cboy hack the world");
  }
  public static void main(String args[])
  {
  k k1;
  p p1=new p();
  k1=p1;
  p1.show(2);
  p1.show();
  }
  }

  Otherwise it will hide the method of base class.

  Hey he is asking in the case of overriding., but you have posted in overloading,why?

  Yes you can do this using scope resolution operator, SRO ( :: ).
  

  
  public class A   //base class
  {
    public void show()
    {
      System.out.println("In base class");
    }
  }
  
  public class B extends A   //derived class
  {
    public void show()   //over-ridden function
    {
      A::show();   //calling the function of base class
      System.out.println("In derived class");
    }
  }
  
  

  And not just this, you can use SRO to resolve other type of ambiguities also like between a global and a local variable with same variable name..

  Polymorphism With Function Overloading is a way out :-
  class a{
  void show(String x){System.out.println(x);}
  }
  class b extends a{
  void show(String x, String y){}
  }
  class c {
  public static void main(String []args){
  a a1 = new b();
  a1.show("base");
  }
  }

  But i wanted over-ridden method of parent class to be called using object of derived class.
  Please do not confuse with over-loading.
  I hope i am clear now.
  
  I have to call an over-ridden method of parent class using object of derived class.
  Is that possible ?

  then there is no way out because if you want object of derived class with overriding it wont work because its the REFERENCE variables who decide which method to call while using function overriding and not the Objects.
