hi there, i'm not that new in java but not an old too :)

I want to learn how to open windows components from java.

e.g
Java Code:
Process exec = Runtime.getRuntime().exec("taskmgr");
i know it opens windows task manager
and
Java Code:
Process exec = Runtime.getRuntime().exec("calc");
opens calculator
executing .exe is not a problem.

Now I want to learn how to open control panel components like mouse, date/time, power options etc.
Please I need Help. That must be a 1 line code or a couple of words trick.

Thanks in advance.
