I have added Path variable 'C:\Program Files\Java\jdk1.6.0_21\bin' in Environment Variables, but it still gives me this error: 'javac' is not recognized as an internal or external command, operable program or batch file when I try to run javac mycode.java. I am going insane, please help. Thanks.

Close the command prompt window and open it again so that the new environment variables take effect.

Of course this step was mentioned in the instructions I linked to the original question. Wonder if he ever read them...

Rename your .java file to my_first.java and try compiling again. The source code file must have the same name of your class, in this case, my_first.

The error message tells you exactly what is wrong. The name of the file must match the name of the class. Rename hello.java to my_first.java and it should work.
