Instance Method Overloading - Polymorphism

[sr shashidhar]

Hi frndz,

My Question is "When we are overloading instance methods" under which polymorphism it comes...? either it comes under Run-Time Polymorphism or Compile-Time polymorphism...?


Example :

class A
{
    void m1() { }
    void m1(int x) { }
    void m1(int x,int y)  { }
}

class B
{
 public static void main(String[] args)
{

   A a1=new A();
  a1.m1();
  a1.m1(4);
  a1.m1(5,8);
}
}

either it comes under Run-Time Polymorphism or Compile-Time polymorphism...?


thanks in advacnce

1. Please EaseUp (←click). Using bold is akin to shouting; and nobody likes being shouted at.

2. IMO, there is no such thing as "compile-time" polymorphism - in fact, the term itself is an oxymoron - but, to answer your question, it is often used to describe method overloading (real polymorphism refers to method overriding).

Hi sr shashidhar, did you not see this part of Winston's reply? Or do you have further questions?

[sr shashidhar]

yes sir,

can anyone tel me what is the difference in the following statements. As i heard its dynamic dispatch, but what makes difference, where and when it is used...?

A a=new A();

B b=new B();

.


thanks in advance...

My apologies, sr. I deleted your duplicate posts, but I have a feeling that you updated the last of them while I was doing so. If so, please edit the remaining one again.
