[BK MEN]

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?


` package apps;


import java.awt.*;

public class Alarm2 extends JFrame implements ItemListener,Runnable{


private Graphics dbg;

JComboBox c=new JComboBox();


Thread t;


int h,m,s;


boolean alarm=false;


String time="";






TextField tf=new TextField("SEX:",10);


Alarm2(){










setTitle("BALVEER");

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


c.addItem("MALE");


c.addItem("FEMALE");


setBackground(Color.GREEN);




c.addItemListener(this);

add(tf);


setLayout(new FlowLayout(FlowLayout.RIGHT,10,195));
