问题 I'm making an application that lets you add files and then compress them but how to get the files from my hard drive or any hard drive for that matter into my application?

问题 I have a JList which uses a DefaultListModel. I then add values to the model which then appear in the JList. I have created a MouseListener which (when double clicked) allows the user to edit the current user number of that person they have selected. I have checked that the actual object of that record is being changed, and it is. The only issue I'm having is getting the actual Jlist to update to show the new values of that object. Snippets of the current code I have are: Creating the JList
