    Default Re: 12 days of xmas??? not showing

    For future reference, please flank your code with the code/highlight tags (see Announcements - What's Wrong With My Code? for instructions). I've edited your post for you this time.

    Now to the problem...you've set the JTextArea text to the variable songString - look closely at the code and determine what this variable's value might be. To be sure, add a System.out.println statement to print out songString and see what its value is...and at the same time, add another System.out.println statement to print out the variable result.
