I am new to Java and I'm creating a clock with time zone. I have a little problem with JComboBox's repaint method. If I put repaint() in my code I can't see the JComboBox in the Applet window, and if I remove repaint() then it is visible. As you know it is very necessary to put repaint() in your code.
Analyse my code and tell me...
What am I doing wrong?

public class Alarm2 extends JFrame implements ItemListener,Runnable{

c.addItem("MALE");


c.addItem("FEMALE");
