import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
/*<applet code="MouseEventClass4" width="300" height="200"> </applet> */
public class MouseEventClass4 extends Applet implements MouseListener {
Label l;
public void init()
{
setLayout(null);
l=new Label("Hello Mouse");
l.setBounds(50,50,300,100) ;
add(l);
addMouseListener(this); //Corrected line
}
@Override
public void mouseClicked(MouseEvent e) {
l.setText("Mouse clicked(# of clicks:"+e.getClickCount());
}
@Override
public void mouseEntered(MouseEvent arg0) {
l.setText("Mouse Entered");
}
@Override
public void mouseExited(MouseEvent arg0) {
l.setText("Mouse Exited");
}
@Override
public void mousePressed(MouseEvent e) {
l.setText("Mouse Pressed no. of clicks:"+e.getClickCount()+"at position
"+e.getX()+","+e.getY());
}
@Override
public void mouseReleased(MouseEvent e) {
l.setText("Mouse Released;# of clicks:"+e.getClickCount());
