Since choice is a local in a different function, you need to pass it as a parameter: public static void calc(int x, int y, int choice) {. }. calc (firstnumber,secondnumber, choice);. Note that your calc method is not optimal: all four case s have the same line in them: System.out.print("Output-" + c);. You could move.
