I'm pretty new to Java Programming, and I'm trying out different ways to make a calculator with the JOptionPane, but I can't get this to work... I'm pretty sure it's something simple.. Here's what I have:
[Java] Calculator V3 - Pastebin.com
And it outprints:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3 at Multiply.Process(Multiply.java:18) at Calculator.main(Calculator.java:17)
