Question : Help Please!
This is the question:
develop a basic calculator that operates on real numbers. The Graphical User Interface
I HAVE DONE ALL THE WORK AND MY CALCULATOR WORKS FINE EXCEPT FOR THIS PART BELOW :
Your calculator's behavior should pretty much behave like the Windows Calculator in Standard mode. In Standard mode, the order that operations are evaluated is that in which they are entered. For example, if the users presses "3", "+", "2", and "*", the display gets the value of the first operation (3+2). Subsequently pressing "4" and "=" results in the running total (4) getting multiplied by 4, yielding 20. If multiple operators are input in succession, use the last one for computation.
CAN SOMEONE PLEASE HELP ME! THIS IS MY CODE:

Answer : Help Please!
You have an extra } just above that method and you have a } missing at the end. You may have inserted your code between the wrong pair of }s.
