How to launch the command-line from a Java application ?

Hi,
I'm new in Java programming , and I would want to open a command-line window from a Java application, and at the opening of this command-line window, I would want the current directory to be a directory specified from my Java application, for instance , if in my Java application , I specify the directory "D:\MyProjects\Project1", I would want that at the opening of the command-line, the current directory is "D:\MyProjects\Project1".
Please, how to do this ?
Thanks.

Take a look at the Runtime.exec() method. Remember that if you change directories in Java it will not affect the running process. You'll have to do that a different way.
