I am trying to build my first GUI, and I wanted to gather input using a JTextField. I have 5 JTextFields that I want to use to gather input, then I want to paste their sum into a non-editable JTextField. I looked online, and found that I have to use an ActionListener. However, I have no clue how that works, and the Oracle website uses tough terminology. Can someone please explain what ActionListener does and how to implement it? Thanks.

There's a whole section in the java tutorials about EventListeners (an ActionListener is a specialised type of EventListener). It would be better if you read that and then asked specific questions about what you don't understand rather than expect somebody to just repeat everything that is in there.
