请问怎样才能让JList有滚动的功能

[crispopo]

有一本书上说，只要将JList包装于JSrollPanel就可以了

但我不知道怎么做，请指教

import java.awt.event.WindowEvent;
import java.awt.event.WindowAdapter;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.JPanel;

public class Test {
private JFrame frame;
private JPanel pane;
private String [] str = new String[20];
private JList list;
private JScrollPane sPan;

public Test() {
frame = new JFrame("JList");
pane = new JPanel();
for(int i=0;i<str.length;i++){
str[i] = i+1+"";
}
list = new JList(str);
sPan = new JScrollPane(list);
frame.getContentPane().add(pane);
pane.add(sPan);
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent windowEvent) {
System.exit(0);
}
});
frame.setSize(600, 400);
frame.setVisible(true);
}

public static void main(String[] args) {
new Test();
}
}

JScroll sPan = new JScrollPane(new JList());
