but i really dnt understand why the error is cuming as invalid method declaration - return type required

public MywindowAdapter(SampleFrame sampleFrame)


//Create a child Frame window from within a applet.

import java.awt.*;
import java.awt.event.*;
import java.applet.*;

//Create a subclass of frame.

class SampleFrame extends Frame
{
SampleFrame (String title)
{
super (title);
//create an object to handle the window events

MyWindowAdapter adapter = new MyWindowAdapter(this);

//register it to recieve the events
addWindowListener(adapter);
}
public void paint(Graphics g)
{
g.drawString(" this is in the frame window:",10,40);
}
}
class MyWindowAdapter extends WindowAdapter
{
SampleFrame sampleFrame;

public MywindowAdapter(SampleFrame sampleFrame)
{
this.sampleFrame = sampleFrame;
}
public void windowClosing (WindowEvent we)
{
sampleFrame.setVisible(false);
}
}

//create a frame window
public class AppletFrame extends Applet
{
Frame F;
public void init()
{
f = new SampleFrame(" A frame window");
f.setSize(250,250);
f.setvisible(true);
}
public void start()
{
f.setVisible(true);
}

public void stop()
{
f.setVisible(false);
}
public void paint(Graphics g)
{
g.drawString(" this is in the applet window:",10,20);
}
}

Thank you but yes there is a new problem as now the error is as -class AppletFrame is public ,should be declared in a file name d AppletFrame.java.

[dswastik]

You have multiple classes in this code. Your file name should be (AppletFrame.java) same as the public class name i.e AppletFrame, and you need to compile it as javac AppletFrame.java
