    What method? More needs to be done than change a method. Without a design coding is a waste of time.i

    What is the design for how the program should work? Decide on what the program should do before writing code.

    Does that code do what you want now?
    What happens when you execute it?

    No it takes ANY draggable source and then rejects all the others. How do I assign it so that sentence only takes "moon" and rejects the other sources?

    it takes ANY draggable source
    How are you testing it to see that it takes all draggable sources? What draggable sources are there in the program to test with?

    Those draggable sources are NOT in the code in post#29 that I was using for testing.

    What are all the Strings in the constructor for the DropTargetTextArea class for in post#33? They were NOT in the code in post#29.

    Why did you change that?

    Did you see my questions about the 4 Strings in the constructor? Why are they there? What does the class do with them?

    it relates to the drop label. i have 4 drop labels and in the DropTargetTextArea any four can be dropped.

    What do you need to fix? What is the program supposed to do? What values does the DropTargetTextArea class need to have to do its job? What is the DropTargetTextArea class's job?

    These are all questions that should have been asked and answered when the design for the program was made.

    the "cat jumped over the moon" label,
    Where is that label? I don't see one with those words in the text.
    The drop location in the code is EMPTY, there is no text in it.

    have 1 only string value which it will either accept or reject
    Yes, that sounds like what it should have and do.

    Rewrite the code so it does that.

    if i was to add another 2 sentences how would i implement this?
    Each new drop target would be a new instance of the DropTargetTextArea class.

    Are you asking how to create an instance of a class? Use a new statement. The current code is full of them.
    For example:
                   JPanel gridPanel = new JPanel(new GridLayout(4, 4, 5, 5)); 
                    JPanel flowPanel = new JPanel();
       ...
          Component droplabel = new DropTargetTextArea("moon", "dog","cat","mouse");

    All those statements create new instances of some class.

    i thought i was doing them wrong and thats why i took them out.
    You are correct, the code I posted was NOT how the code is supposed to be. I just copied some code from your last post to show you how you have used new statements many times in the code.

    The constructor should have the String that the instance of the class will accept. Each instance can have its own String.
