How to add JList to Scroll pane in Java?

To add JList to Scroll pane in Java, use JScrollPane:

JList list = new JList(sports);
JScrollPane scrollPane = new JScrollPane(list);

import javax.swing.*;
class SwingDemo extends JFrame {
   static JFrame frame;
   static JList list;
   public static void main(String[] args) {
      frame = new JFrame("JList Demo");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      String sports[]= {"Tennis","Archery","Football","Fencing","Cricket","Squash","Hockey","Rugby"};
      list = new JList(sports);
      JScrollPane scrollPane = new JScrollPane(list);
      Container contentPane = frame.getContentPane();
      contentPane.add(scrollPane, BorderLayout.CENTER);
