Hi faisal_Sharif,
Exception in thread "main" java.lang.NoClass DefFoundError: HelloWorld/javaoccurs because java didn't find HelloWorld.class which is not genertated when you given javac HelloWorld.java command.
As Aakash has given a link... hope it will help you.
But I have a small doubt:
If the path is not set than instead of following exception:
Exception in thread "main" java.lang.NoClass DefFoundError: HelloWorld/javafollowing exception should come:
'java' is not recognized as an internal or external command, operable program or batch file.on Windows OS.
