Hello! I am trying to make it read the users input when they press the Send button under actionPerformed and compare the strings in a separate method, commandList. Most of it is working but when I type 'register' it tells me it's an unrecognized command. Thanks!

it tells me it's an unrecognized command.

What is the value that the computer is comparing to determine if what was entered is a valid command?
Print it out so you can see it and/or include it in the error message.

Where is the text: "unrecognized" shown in the program? I can not see it.

inputText = gameArea.getText();

should afterwards have this applied

inputText = inputText.trim().toLowerCase();
