4. Introduction to applet :-
 Small java programs that are primarily used in
internet computing.
An applet can do many things such as arithmetic
operations, display graphics, play sounds,accept
user input, create animation, and play interactive
games.
Java applets can now therefore make a
significant impact onWorld WideWeb.
We can do the graphics programming using
applet

5. Developing and testing in applet:-
 write an applet code (.java file)
 Creating an executeable applet (.class file)
 Designing a Web page using HTML tags
 Preparing <APPLET> tag
 Incorporating <APPLET> tag into the webpage
 Creating HTML file
 Testing the applet code in CMD

6. Applet
 A Java applet is a small application which is
written in Java and delivered to users in the
form of byte code.The user launches the Java
applet from a web page, and the applet is
then executed within a JavaVirtual Machine
i.e JVM in a process separate from the web
browser itself.

7. Building APPLET CODE :-
Applet code uses two classes, APPLET &
GRAPHICS from our Java class library.
The applet class is contained in the java.applet
package.
Applet methods are:-
I. init()
II. start()
III. paint()
The applet code imports java.awt package
which contains the Graphics class.
