• If you want display a choice list, then create a new JList. Use the setListData method, with a vector-of-strings argument, to establish the contents of the choice list.
• If you want to determine which element is selected from a choice list, then implement a listener class that defines a valueChanged method, then obtain the selected element's index inside valueChanged using getSelectedIndex, and then use addListSelectionListener to attach a listener instance to the choice list.
• If you want to display a choice list with scroll bars, then embed your choice list in an instance of the JScrollPane class by instantiating the following pattern:

  new JScrollPane(choice list) 
  

  and then add the scroll pane, rather than the choice list itself, to the surrounding applet or frame.
