Well, it was probably an aesthetic decision on the part of the Java developers, and consider this: The server needs to access some of the applet's attributes, so doesn't it make sense that the applet is public? If the applet was private, nobody would be able to access it.

Write a program to create an applet with red back ground and display the message welcome to the world of applets write its HTML document also specify width and height to the applet?
import java.applet.Applet; import java.awt.Graphics; @SuppressWarnings("serial") public class AppletTest extends Applet { public void paint (Graphics g) { g.drawString("WELCOME TO THE WORLD OF APPLETS", 100, 25); setBackground(java.awt.Color.RED); } } <HTML> <HEAD> <TITLE> AppletTest</TITLE> <BODY> <CENTER> <APPLET CODE = "AppletTest.class" WIDTH = 400 HEIGHT = 100 </APPLET> </CENTER> </BODY> </HEAD> <HTML>
Write a program to show the applet life cycle?

How do you run applet program?
By Embedding it into a HTML page, create a new file with the extension .html (like app.html) insert following code: No Java 2 SDK, Standard Edition v 1.4.2 support for APPLET!! Adjust the code for your applet file (can't help there i am not a java programmer) or just use : No Java 2 SDK, Standard Edition v 1.4.2 support for APPLET!! but i recommend the first because the applet tag is deprecated and not supported in XHTML

How a class in java declared default?
default it is public type
What is public private protected variable function?
The public, protected and private keywords only apply to object oriented programming languages. They are used to determine the accessibility of specific class members and their bases. Private members are only accessible to the class and to friends of the class. Protected members are the same as private but are also accessible to derivatives of the class. Public members are accessible to all code. When applied to base classes, the public, protected and private keywords can be used to either maintain or reduce the accessibility of the base class members (but never to increase their accessibility). When declared public, the accessibility of the base class members remains as defined by the base class. When declared protected, the public members become protected members. And when declared private, all members of the base class become private members. As well as defining the overall accessibility of the base class members, the accessibility of individual base class members can also be specified.
Abstract class can be private?
A class can either be default or public it can never be declared as private, so the question of abstract class at the file level does not arise. But an inner class can be declared private and abstract as well.

Applet class is not inheriting AppletContext interface but in Applet Class getAppletContext method is returning AppletContext object how is it possible?
There's nothing in Java that says that a method in a class can only return object types that the class inherits from. Your Applet is running in some sort of environment (a context, if you will). The Applet.getAppletContext method returns an AppletContext object which describes this environment.
