How to open mycomputer and control panel on button click?

I am developing a application in j开发者_StackOverflow社区ava swing? In which I need a notedpad. I want to give some extra feature in that notepad, as I want to open mycomputer, control panel, browser etc. directly from the notepad menu? Can you help me someway to do this task?

Also consider the features in java.awt.Desktop.

You can execute external programs in Java with Runtime.getRuntime().exec().
