>how to set path?
You needto set the bin directory of the java installation directory in your PATH. So if you installed in /opt/java, put /opt/java/bin in your PATH. You set it the same as you would for anything else you want to set in your PATH. The exact steps/syntax to do so may vary slightly depending on what shell you use. Do a Google search for setting PATH in Linux for your shell and you should get plenty of hits to help you.

>how to compile and run? are the commands are same?
Yes the commands are the same on Unix, Linux, Windows, etc. javac and java

>in which editor, i have to work (like command prompt in windows).
You can edit using any plain text editor: vi, vim, emacs, EditPad, etc. The editor can be command line or GUI based, as long as it is a plain text editor (i.e. saves files in plain text and not binary, and doesn't insert any formatting or additional markup). You will need to use a command line to compile and run from.

One more thing, about editor.
I highly recommend JEdit.
It's written on java and for java, so it can run on any platform (including Linux and Windows) and has some useful features for java programming.
You can download it for free at
www.jedit.org

Whenever a new reply is added to a thread, the whole thread moves to the top of the list. This means that telling someone to look at another thread "2 lines down" is typically not very helpful. At the time that I read this thread, it was 3 lines further down. By the time I post this message, it will be even further away. This just means that you should provide a link directly to the thread in question: check out this thread.
