applet related confusion

in the book its said that applet can be used in source code too,instead of writing it again ang again in HTML pages...

and the code was like follows

import java.applet.Applet;
import java.awt.*;

/*<APPLET
Code=applet4.class
WIDTH=200
HEIGHT=200>
</APPLET>
*/
public class applet4 extends Applet
{
public void paint(Graphics g)
{
g.drawString("Hello",60,100);
}
}

how how will this code used in any HTML page?

Moving to Applets.

Rob Prime didnt get you

It won't be used in any HTML page - it's for development and testing purposes only. If you embed the applet tag in the Java source code like his, then you can use appletviewer to run the applet by typing "appletviewer applet4.java". That's because appletviewer doesn't care about the rest of the file - it only looks for the applet tag.

If you want to deploy the applet for others to use, then you do need a proper HTML page (which would contain the same applet tag).
