Most specific method..

[Vidhya Praba]

Hi All,

Thanks for this wonderful forum...Its been so helpful to me, I have finally got the nerve to join it!!!

I found this program in a mock exam. Could someone please help me in understanding this logic...

    
class Parent
{
void amethod(int i)
{
System.out.println("Inside Parent, i = "+i);
}
}
 
class Child extends Parent
{
void amethod(long i)
{
System.out.println("Inside Child, i = "+i);
}
}
 
public class testaMethod
{
public static void main(String[] args)
{
Child c = new Child();
c.amethod(10);
}
}

I'm getting compiler error saying amethod is ambiguous in Parent & Child class. But if I swap the method types, ie., long in Parent & int in Child, then it executes fine & amethod in Child gets called. Why is this happening?

Hmm not sure where your problem might be. I copied the code just like it was presented and ran it on a 1.5 compiler and it seems to be working fine. Works fine with source -1.4 too ( like it should ). Are you sure that this is the right code where you are facing errors ?

Mine is still 1.3!!! so, i'm downloading 1.4.2 to check it...But the similar question can be found in the overloading & overriding objectives in the following mock exam link..
