I am fairly new to java programming,and I wrote a program that functions as a calculator. Everything works, but I have to do error handling which entails me writing an error message if the user enters a letter of the alphabet instead of the number. My problem is I don't know how to say that num1 is not equal to any character of the alphabet.
