How could I allow only unique strings in a JList?
I have a JList that holds a bunch of strings . I would like it to act like a Set , so that it will only hold unique values . Is there any way to achieve this without checking that a new string doesn't already exist there ?
You can set your own ListModel via JList#setModel(ListModel) which might be backed by e.g. a HashSet instead of the Vector which is used by default.
