}

either minimize the code you show, or be more specific of the problem. what is the part of the code we need to focus on?

Empty the receipt String at the beginning of the actionPerformed. Each order you run by all the checked items and, if checked, append their value to the already existing String.

You can set the value of a JTextArea by using its setText() method. You could call that at the end of the same actionPerformed.
