I have JList filled with names and a JButton which when clicked deletes the selected item in the JList. The item is now longer in the array that fills the JList because the array is written out and the item is missing but the missing item is still on the screen. How do I GET the item to disappear from the screen?

Thank you COULD you paste the source code of what you have now, so that we may take a look?
Also, now this isn't for a HOMEWORK assignment now is it?/*
