If it were me, I'd have it as a static field for the entire class, e. Much easier, and we've reduced the complexity of our code. This sounds like a fun project! Even just add might work, though that might be a bit misleading and lead someone reading your code to believe that all the method does is add two numbers, when really the core functionality is user interface. Eventually you can add something to this so that it distinguishes the operators separately and the user can write an expression rather than answer questions about the expression, I think that is really the goal right? So for example, your addition method might be better named performAddition or some such. } This would also be a perfect use-case for enums, but that my be getting a bit too complicated for a starting project. Small final note: I think you have a bug. .

I think you should ask for the first number then ask for the operation and then ask for the third number. You really only need to do this once. You do this in multiple places. I hope you find the comments below useful as you progress. I have made a basic calculator using methods. If I were going to calculate something I would do it in this order: Number1 then operator then Number2 This way I know what I am doing, especially when playing with division. This is my first attempt at using methods and would like to see if I can improve on this as there is a lot of repeated code.

Some other small things You should consider using a switch statement on your choice variable: switch choice { case 1: performAddition ; break; case 2: performSubtraction ; break; case 3: performDivision ; break; case 4: performMultiplication ; break; default: System. . . . .
