Question

I am having a methods like
// Base Class

public void foo(long A, long b,long c)
 {
    //Implementation 1
 }

//Derived Class

public void foo(long AA,long b,long c)
  {
   //Implementation 2
  }

I would like to what is wrong with this design ?
FYI:
I am using Proxy pattern for my design

Thanks

The name of the parameters doesn’t matter. Come run-time there is no way for java to tell which method you wanted to call at a given time. To overload methods the signatures have to be different so either there must be a different number of parameters or the parameters must be in a distinguishable order i.e. String, int and int, String.
