Execution process:-

1- develop the applet code(.java)

2-compile the applet code(.class)

3-write the basic HTML structure format

4-develop the APPLET tag for the applet

5-insert the APPLET tag in HTML code

6-run it using appletviewer (appletviewer ______.htmlfile) or

                       double clicking on (.htmlfile) you created.
