import java.awt.*;ChoiceAction() : Code illustrating item listener on Choice is written here
import java.awt.event.*;
class ChoiceAction extends Frame
{
Choice c;
Label l;
public ChoiceAction()
{
// Set frame properties
setTitle("Choice with ItemListener Demo");
setSize(400,400);
setLayout(new FlowLayout());
setLocationRelativeTo(null);
setVisible(true);
// Create choice
c=new Choice();
// Create label
l=new Label();
// Add items
c.add("Apple");
c.add("Mango");
c.add("Guava");
c.add("Orange");
c.add("Pineapple");
c.add("Grapes");
// Add choice
add(c);
// Add label
add(l);
// Add item listener
c.addItemListener(new ItemListener(){
public void itemStateChanged(ItemEvent ie)
{
l.setText("You selected "+c.getSelectedItem());
}
});
}
public static void main(String args[])
{
new ChoiceAction();
}
}
