:( I Just can't get this code to work (Help plzzzz)

Question

I was assigned a final exam project, but most of the stuff we never actually saw in class, so I just have to figure it out for myself.
The part I'm stucked in (among other stuff) is:
room = new JLabel[4];
selec = new JRadioButton[4];
roomg= new ButtonGroup();
         for(int i = 0; i < 4; i++) {
              room[i] = new JLabel(arean);
          selec[i] = new JRadioButton();
          selec[i].addActionListener(this);
          areap.add(room[i]);
          areap.add(selec[i]);
          roomg.add(selec[i]);
          areap.setBorder(new TitledBorder(""+arean[i]));
This part of the code successfully created a group of JRadioButtons each with the names previously established in arean[ ]. However, I'm supposed to make it so that whenever I press any of the RadioButtons, the border of the JPanel changes as well. As it is, Java will put only the last name, and won't change it as I click the different JRadioButtons.
I'm not sure if I made myself clear, so if anyone is interested in helping me and needs further information, plz let me know.
Thanks in advance.

If it's an array of Strings of area names, then the
append to an empty string in this line of code:
              areap.setBorder(new TitledBorder(""+arean)); is extraneous (as
well as being a nasty idiom anyway, IMHO). I see
that you removed it in your example...
I agree that the empty string is a nasty idiom (hence my removal of it).  I figured arean had to be an array of Strings, if it is passed to the JLabel constructor (because toString on an Icon would probably be usely).
