My first java applet program

              This is a blog about embedding a simple java applet inside a web page. A java applet is actually a runnable java program that can be embedded in a website for showing some graphics or making the web page interactive.

Then this runnable is embedded in the web page in a mechanism similar to embedding pictures inside the html file using html tags.

So before you starting the applet programming you need a java programming environment within your system including javac compiler and Java Runtime Environment.

I started doing the applet programming as it is a topic in my Web Commerce paper. Still i didn't got enough time to invest for it, but here is the basic things that I came across while discovering the kick of applets with my ubuntu box... 

1. First open up your text editor and paint all the code inside it, save it with .java extension. Use the code snippet  below or download from here,
