    Question Updating JList

    I have a program that lists files in a directory (on a JList). I also gave an option to delete the file the user has selected. However, when the file is deleted, the list doesn't update. How would I get it to update automatically after the file is deleted (preferably by reloading the list somehow)?

    That really depends how you're storing the files to display. In a model? In an ArrayList? Something else?

    the full file path for each file is stored in an array. the when the JList is initiated... JList name = new JList(Array);

    The JList tutorial contains information on removing elements from a JList: How to Use Lists (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components)
