Also I would like to know, is there any difference when I create JAVA files in NETBEANS or simple notepad. What is better for me.
Should I add the java environment variable path here too, this thing is functioning fine
Now the path environment variable has been sorted out quiet well, now please tell me how to remove this error
Exception in thread "main" java.lang.NoClassDefFoundError:

Use a text editor and not an IDE if you are beginning. I can gather you are using Windows, I suggest Notepad++, stay away from the crappy notepad bundled in Windows.

Right click, My Computer, then
in the Variable Value entry, add entries for your Java directory, C:\Program Files\Java\jdk1.6.0_20\bin, the delimiter is ;. Do not delete the previous entry, just add the new try.
And oh while executing, use java program not java program.class

Er you don't write %PATH% , in that dialog box :/
Try to search and get the default path used in Windows and append your java directory.
Paste this: %systemroot%\system32;%systemroot%;%systemroot%\system32\wbem;%PROGRAMFILES%\Java\jdk1.6.0_20\bin
Also Post the source code of the program to know the context of the error.

Either name your file as HelloWorldApp.java or name the class as class HelloWorld.

Make sure your class name and the file name is same....

Nope. If you know OOPS concept, it is easy to start with Java. But one must know procedural language before they start any language. So C is a basic, but it is not mandatory to start with.

Learning C and C++ will make you comfortable in adopting any other programming language.

I have been working for a few Weeks with Python, Python is a good Language for Non Programmer to get through with concepts. But I was keenly intrested in Java, so I skipped Python after Basics and Started reading JAVA, but I am unable to run the most basic program, though I tired running the program in Netbeans IDE and there most of programs works so easily.
I tried renaming my file, but its still not working giving out the same error.

You still not able to execute a java program? With Netbeans you can?

Yes Just write the program codes in NETBEANS IDE and Press Run Button, and It gives me the right output.

As it always. But for a beginner, using IDE is not a good practice. Then you might possibly loose the chance to know, how to setup classpath etc. So just d/l the latest jdk , install it, use Edit Plus or Notepad++ to write code, run it in command prompt.
And after u get a grip in Java, go for Eclipse IDE.

I am removing NetBeans IDE
Also I upgraded my Java SDK from 20 to 23
