import java.awt.*;
import java.applet.*;
public class TestWindow extends Applet
{
Window w;
Frame f;
public void init()
{
f = new Frame("this is a frame");
w = new myWindow(f);
w.setLocation(300, 200);
w.setSize(300,100);
w.setVisible(true);
}
public class myWindow extends Window
{
myWindow(Frame parent)
{
super(parent);
}
public void paint(Graphics g)
{
g.drawString("this is a window with a warning message", 20, 30);
}
}
