problems trying to view the contents of a text file in JTextArea

[warship]

hello.
I’m having difficulty trying to view the contents of a text file in a JTextArea. when i run the following program, i press the View Order button (program and text file are in a .zip folder that was attached to this message). but no data from the Order.txt file is being displayed in the text area when it should be. what can i do to get rid of this problem?
thank you very much for your help.

You are writing every time the content, you don't add new lines.
I think that the last thing that it read is "\n" or some null string.
