import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class KeyAdapterExample extends JFrame {
    public KeyAdapterExample()
    {
        addKeyListener(new Adapt());
        setSize(200,300);

        }
    }
    public static void main(String args[])
    {
        KeyAdapterExample bt = new KeyAdapterExample();
        bt.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
