Help with display glith using JList

Question

Hi, first post so bit of background - I'm teaching Java at the moment, am fine with command line but am dabbling more with Swing, despite certain glitches I always get ( e.g. the 7-segment display last year) but anyway....
I've been trying to develop a little app that picks random boxers for a computer game. My current problem is that i am trying to add custom boxers and then update the JList and repaint the frame. When I add a boxer i can see it adding to the list, however it is unreadable and displayed too small.
Forgive any bad coding etiquettes - its very much a work in progress from a relatively poor programmer ;)
theBoxers is a JPanel containing the JLists, aWindow is the JFrame, customButton is a button to add a custom fighter - this gets a name from a field, and a weight from a combo box, adds it to an array and then attempts to add it to an array, then re-generate the lists
customButton.addActionListener(new ActionListener()
            public void actionPerformed(ActionEvent e)
                    addCustom(customCombo.getSelectedIndex(),addCustomName.getText());
                         System.out.println(customCombo.getSelectedIndex() + addCustomName.getText());
                         theBoxers.repaint();
                         aWindow.repaint();
public void addCustom(int theWeight, String theName)
          switch(theWeight)
               case 0:          featherCustoms[featherCustomsSize]=theName;
                              featherFighters = new JList(featherCustoms);
                              featherCustomsSize++;
                              break;
               case 1:          lightCustoms[lightCustomsSize]=theName;
                              lightFighters = new JList(lightCustoms);
                              lightCustomsSize++;
                              break;
               case 2:          welterCustoms[welterCustomsSize]=theName;
                              welterFighters = new JList(welterCustoms);
                              welterCustomsSize++;
                              break;
               case 3:          middleCustoms[middleCustomsSize]=theName;
                              middleFighters = new JList(middleCustoms);
                              middleCustomsSize++;
                              break;
               case 4:          lightHeavyCustoms[lightHeavyCustomsSize]=theName;
                              lightHeavyFighters = new JList(lightHeavyCustoms);
                              lightHeavyCustomsSize++;
                              break;
               case 5:          heavyCustoms[featherCustomsSize]=theName;
                              heavyFighters = new JList(heavyCustoms);
                              heavyCustomsSize++;
                              break;
               default:     System.out.println("Not Added");
                              break;
     }

Awww, its nice that DB has someone to comeback and carry on a discussion.....long after its over.
The problem here seems to be your lack of understanding between what a teacher or what an 'instructor' is.
From the way you speak, an instructor appears to be someone who is technically skilled in both coding and teaching Java as a programming language, designed for people who wish to code in Java.
A Teacher is someone who must deliver a wide range of subject knowledge to a wide range of abilities, including those who were unable to pass High-School exams. They are responsible for pitching the subject at the correct level for the student, whilst also teaching towards passing the exam, and ultimately gaining a qualification.
The computing course i am currently teaching does not require OOP, but as Java is the language i was taught at University, and is still often used in our University's, I chose it. I don't pretend to be the best programmer in the world. But I do know that I am teaching the pupils the correct basics, at a higher level than is probably required, to give them the right approach at university. also, this is whilst teaching a large amount of theory.
Whether you agree, or disagree, matters not to me as I think you would be unfamilier with the specification I am currently teaching to, or what area's of study need to be taught. The exam board appears happy, as do past students who are now well into their university course, as did my marker when i achieved my degree.
The code posted in the OP (as stated earlier) had nothing to do with displaying my coding abilities, nor did it display the technique's I use when teaching students. It was a small sample of a program which included a JList which was not displaying properly. I tried to include the whole code but it was too big, therefore it was cut down.
It was a work in progress which i now have working. So now i can look at it again in terms of programming structure. It appears I have made a mistake asking for assistance on here, as instead I got a lecture, with very little insight on your part as to my situation or the nature of the problem/solution.
At the end of the day, each to his/her own opinion. What I will say is that when someone requests help, positive feedback/criticism is well recieved along with instructions/guidance on how the problem can be solved. I feel that I received none of this on here, but this is what I will always provide to the students I teach.
Not everyone is a full-time Java programmer or has the time to hit the highest expectations.
