Hello,
I just wanted to know, is there a way to get a list of processes which are currently running in the Operating System.
Thanks...

I doubt there is a platform-independent way to do such a thing.
In any case, I'm moving this to the Threads and Synchronization forum, where folks are most likely to have an idea...

By the way, why would you want to do such a thing?

There's no Java API for this. You have two choices: a platform-dependent JNI function that uses the native OS's mechanism for getting this list, or using Runtime.exec() to run some platform-dependent program that returns the list as text and then parsing the result.

You might look at this Win32 API fuction:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/enumprocesses.asp
then, follow the links for code examples, etc. And get more info on process-relevant part of Win32 API here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/process_and_thread_functions.asp
And you need to wrap this stuff in JNI, of course...

...and using pure Java you can track (to some degree) only the processes which your application have started by callimg Runtime.exec(...) If you need to track other processes, it will not work for you.

Hello,
I am facing a problem. The link above which was given to me, provided me a source code written on C or C++. Could you please tell me which software do I have to use to run the program.
Thanks....

C/C++ development tool like Microsoft Visual Studio (IMHO overkill for your task), or "gcc" http://gcc.gnu.org/

Bloodshed's Dev C++ is pretty easy to use, and it's free.
If you've further questions on C/C++ development, let me suggest that you mosey on over to Gregg's forums dedicated to the subject.
