Hi Friend,

Try the following code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class ComboBox extends JFrame {
JComboBox combo;
JTextField txt;
public static void main(String[] args) {
ComboBox b = new ComboBox();
}

public ComboBox(){
String course[] = {"MBA","MCA","Others"};
JPanel panel = new JPanel(new GridLayout(2,1));
combo = new JComboBox(course);
combo.setEditable(true);
combo.setBackground(Color.gray);
combo.setForeground(Color.red);
txt = new JTextField(10);
panel.add(combo);
panel.add(txt);
add(panel);
txt.setVisible(false);
combo.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent e){
if(e.getSource() == combo) {
if(combo.getSelectedItem().equals("Others")){
txt.setVisible(true);
}
else{
txt.setVisible(false);
}

}
}
});

pack();
setVisible(true);
}


}

Thanks
