Have a read of the JavaDocs for Runtime.exec. Also, have a search through this forum for references to Runtime.exec. You should find plenty example code.

Well I tried but none of line 1, 2 or 3 starts a command prompt. I think from command prompt, I am running this program, so thats why it won't start a new process.

What happens if you type those commands into a prompt? Do they open a new command prompt?

It does nothing. With the above code it does not open a new command prompt.

Right. So the problem isn't with Java, it's with your use of the command line. First you should set out to discover what command will create a new window. A simple web search led me to this handy reference. Once you have the command, you'll still need a command interpreter to run it, so your exec line should include a call to it. Let us know what you try and if you are still stumped.
