To add a user-defined array of choices to a JList in Swing, you can follow these steps:

  1. Create a JList instance and a DefaultListModel to hold the data:
JList<String> list = new JList<>();
DefaultListModel<String> model = new DefaultListModel<>();
  1. Create an array of choices and populate the DefaultListModel with the array elements:
String[] choices = {"Choice 1", "Choice 2", "Choice 3"};
for (String choice : choices) {
  1. Add the JList to a JScrollPane to enable scrolling if needed:
JScrollPane scrollPane = new JScrollPane(list);
  1. Add the JScrollPane or the JList directly to your Swing container:
frame.getContentPane().add(scrollPane); // assuming "frame" is your JFrame instance

By following these steps, you can create a JList with user-defined choices in Swing.
