package hostel;
import java.awt.*;
import java.awt.event.ComponentListener;
public class Screen1 {
public static void main(String [] args)
{
Frame frame= new Frame("Hostel Management");
Button button= new Button("Profile");
frame.add(button);
frame.setLayout(new FlowLayout());
frame.setSize(500, 300);
frame.setVisible(true);
frame.addWindowListener(new windowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});
}
}

Check frame.addWindowListener() java doc. It says that it accepts
WindowListener() not WindowAdapter.
Your method snippet could be like
frame.addWindowListener(new WindowListener() {
@Override
public void windowOpened(WindowEvent e) {
// TODO Auto-generated method stub
}
@Override
public void windowIconified(WindowEvent e) {
// TODO Auto-generated method stub
}
@Override
public void windowDeiconified(WindowEvent e) {
// TODO Auto-generated method stub
}
@Override
public void windowDeactivated(WindowEvent e) {
// TODO Auto-generated method stub
}
@Override
public void windowClosing(WindowEvent e) {
// TODO Auto-generated method stub
}
@Override
public void windowClosed(WindowEvent e) {
// TODO Auto-generated method stub
}
@Override
public void windowActivated(WindowEvent e) {
// TODO Auto-generated method stub
}
});
}
Define TODO operations.
