Hello fellow java programmers! I have completed my Wireless rover/user controlled robot. I would like some help though. I am not a networking IO's guy, for i have just started using it only a day before building my rover. This may be different then many posts, for this all works! but, not very effectively. Please help me improve! code recommendations?

class Main extends JFrame{

    public void frameSetup(){
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Setup s = new Setup();
        add(s);
        s.run();
        setSize(200, 150);
        setResizable(false);
        setLocationRelativeTo(null);
        setVisible(true);
