About Checkbox

Can anyone please let me know how to get the state of the checkbox and to set the state of the checkbox in runtime.  Also how to detect the checkbox items.

A detailed code in this regard will be very useful for me.

// Save this file in CheckBoxTest.java
// Compile and run it
import java.awt.*;
import java.awt.event.*;

public class CheckBoxTest extends Frame {
      Label lb;
      Checkbox cb;
public static void main(String args[]){

      CheckBoxTest cbFrame = new CheckBoxTest();
      cbFrame.setSize(300,400);
        cbFrame.setVisible(true);
}

CheckBoxTest(){

      setLayout(new FlowLayout());
      cb = new Checkbox("Check and Uncheck me");
      lb = new Label("Check box is not set");

      add(cb);
      add(lb);
      cb.addItemListener(new cbListener());
}

class cbListener implements ItemListener{
      public void itemStateChanged (ItemEvent e){

         System.out.println("State Changed");
         if (cb.getState())
              lb.setText("The Checkbox is set");
         else
            lb.setText("Check box is not set");
      }
   }

For setting the state in runtime , you can do cb.setState(true) or cb.setState(false) anywhere in the program where the logic permits. (cb is the checkbox in the above program).
