This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have installed fedora linux version 6, but i donno how to execute the Java programs in Fedora Linux. If anyone has the procedure for the same pls give me the link or some useful details regarding the same.
we can't tell if you have been given an executable jar file to run, a compiled class file, or whether you are working with the source code.
we can't tell if you are comfortable with working from a shell (and if so, are you using the bash shell) or are you looking at the X Windows System (probably running the Gnome window manager since that is default on Fedora Core 6) and trying to work out what to do next
we can't work out whether you are using the JDK that comes with Fedora Core 6 (GCJ - roughly equal to Sun's JDK version 1.4) or whether you have installed a later version (hopefully from Sun's site).
we can't tell whether you are familiar with editing files on Linux systems - are you happy to use vim or emacs (or their X11 equivalents) or kedit or kate or ....?
Do you see why it is so hard to even start helping you?
As an aside, some people look at these sorts of issues and try and claim that Linux is a failure. Not so. The first point would still have to be established before we could begin. The 2nd and last points become slightly easier under Microsoft Windows since they do not give you options - you will use cmd.exe, and notepad.exe is the only consistent editor we can talk about. And since Microsoft do not distribute anything like a Java compiler, you will have had to have downloaded from Sun - whereas Linux tries to give you a Java compiler from the moment you complete your installation, even if it is not the official release.
First of all for your first question, I m trying to execute compiled class file and i m working in vim and i know very little about linux file system cos i m very new to that OS, do i have to install JDK in Linux cos when i gave command Javac HelloWolrd.java it could not compile the same. I think this post is clear to help me, if this is not clear pls tel me i will try to give you more details on the same.

Well that works on Windows.
Badri, unfortunately it won't work on Linux. In Linux everything is case-sensitive. So it does need to be exact, and in Java that Java compiler is all lower case. Actually in most cases, probably all, all commands will be all lower case on Linux, it is kind of the standard there.
Good Luck, I admire your courage to jump into using a new OS.
Thank you very much all you people for helping me to learn java on Linux. Please give me more details which will help me to learn early. It is very interesting to work in Linux cos its new to me and i m very eager to learn new things. I did not know that i have to install JDK in Linux, now i will install and try to execute small programs in it.
