    That's just logic:

    if ( imageMatchesWords )
    {
        // accept it
    }
    else
    {
        // put it back where it came from
    }

    Writing Drag and Drop code can be quite complicated if the components don't support it directly. Maybe you should look at selecting objects with mouse clicks instead of DnD.
    If you don't understand my answer, don't ignore it, ask a question.

    I think its possible but I have no idea how hard it would be for you to do it. I wrote some DnD code 8 years ago and haven't worked with it since then.

    i have managed to do drag the selected text into a textarea, however i will need to change to this to a label.
    I need the text which the user drag to match with the image and if it matches to go in the text area if not then to go back on the panel.
    This is where i am going to struggle now.

    someone above gave me a tip and said it was easy, but i may need some help. any tips

    What is the source of the text that is being dragged? Have you written a small test program that does a drag and drop from a source to a target?

    The posted code is missing all the import statements.

    What is your next step?

    The posted code must be very old. It uses awt classes vs swing

    First you need to make a component that is a target for a drop gesture. The code for the drop location would look at the "text" that was being dragged and make the decision if it matches the target site or not.

    What code is that error message for? The posted code has about 165 lines and is named: DragAndDropExample.
    Do your testing on the posted code BEFORE making a larger program. Work out the coding techniques with a small program first.

    DropTargetjlabel cannot be converted to java.awt.Component
    You need to post all of the code.
    And all of the error messages. You mention 3 errors but only post the text of one.
