    Unhappy New line in TextArea(clicking on radiobutton)

    This is the output:
    Untitled.jpg
    This happens when I input "1" in the quantity textfield.
    (The quantity textfield turns null after inputing a value)

    But when I put "1" in the quantity textfield and click Oranges, it overwrites the Apples.
    Untitled1.jpg

    WHat i wanted to happen is that it'll tally my selections. Like this:
    ((I ONLY EDITED THIS))

    These are my codes so far:
    import javax.swing.*;

    Please avoid shouting in the forum.

    If you are serious need of quick help, consider replying to Norm who tried to help you in your previous question on this site which you have abandoned. Many here will avoid helping folks who abandon threads as we feel that they are likely to abandon and ignore this one, so why put in the effort to help?
