public class test extends japplet  {     private int applet_width = 500, applet_height = 400;     private jtabbedpane tpane;    private createpanel createpanel;    private countpanel countpanel;    private vector athletelist;     //the method init initializes applet pane 2 tabs    public void init()     {      //list of athletes used in every panel     athletelist = new vector();       //register panel uses list of athletes      countpanel = new countpanel(athletelist);       createpanel = new createpanel(athletelist, countpanel);       //create tabbed pane 2 tabs      tpane = new jtabbedpane();      tpane.addtab("athlete creation", createpanel);      tpane.addtab("medal count", countpanel);      getcontentpane().add(tpane);      setsize (applet_width, applet_height); //set applet size      setpreferredsize(new dimension(applet_width, applet_height));      setmaximumsize(this.getpreferredsize());      setminimumsize(this.getpreferredsize());     } } 

help appreciated.many thanks
