System call in Java

Can we make calls to programs written in other languages using java. Is it possible that we can call Unix OS commands and Utilities using Java.

Yes; with JNI and Runtime.exec(). Readign this article may prove useful: http://www.javaworld.com/jw-12-2000/jw-1229-traps.html

you can do that with

Process p = Runtime.getRuntime().exec(command);

there are many overloaded exec methods. see the api docs here.

but before you do that read this article for problems with exec and how to avoid them
