Overloading doubt

[ketan khairnar]

Why it is necessary(must) for arguments to differ?

[Kris Reid]

overloading example

public void methodA(int a) {}
public void methodA(int a, int b) {}

they need to have different signatures so it knows which to call.
if they where
public void methodA(int a) {}
public int methodA(int a) {}

how the compiler know which method you are after?

Hope that makes sense
