Times group Interview questions: Method overloading/overriding

is it overloading? will it compile, if not then why ?
  public void show(String a){
    //.....
    //...
  }



   public int show(String a){
    //.....
    //...
   }


 Solution: It is not mothod overloading as argument list must be different. It will not compile and compiler will give duplicate method error.
