How to close other Windows Programs from a Swing GUI ?

Question

I am making this really simple login program that once a user has successfully entered a username and password, and this is checked through a mySQL database , I run an Internet Explorer Windows.
Now I am trying to setup a logout button and when they push this button ideally the open Internet Exlporer Windows would close.
Does anyone have an idea how to do this is Swing or the wider java language or maybe even something built into windows ?

It's as simple as obtaining references to the Windows and calling dispose() on them. How you obtain the references is entirely up to you. For example, you can create a List to hold all the children windows/dialogs that are created. And on logout you iterate through the list, dispose the child windows, and remove them from the list. Or maybe the child windows can add themselves as listeners to the logout button. When it's clicked and an ActionEvent is fired, the child windows can dispose of themselves automatically.
