Undo depends on the kind of action that you want to undo. Do you mean the text that was entered? If you want to undo letter by letter, you can implement a Que system that records every letter entered in a JTextField. Then when the user undoes, you take the last letter add it and remove it from the JTextField (or word, depending on your requirement).
