Which tag may I use to include a code fragment in the javadoc

Question

I want to include a fragment of my code in the javadoc, but I want it formatted in the Java style ..
how can I do that ??
like as:
* public Demo() {
* super("demo");
* UIDefaults defaults = UIManager.getDefaults();
* for(Enumeration keys = defaults.keys(); keys.hasMoreElements() ;) {
* Object key = keys.nextElement();
* System.out.println(key + ":\t\t " + defaults.get(key));
*/

Answer 1

It did not worked:
* The following code print out the complete UIManager values:<br>
* <code>
  import javax.swing.*;
  import java.util.*;
  import java.awt.*;
  public class Demo extends JFrame {
         public static void main(String[]args) {
                 Demo p = new Demo();
         public Demo() {
                 super("demo");
                 UIDefaults defaults = UIManager.getDefaults();
                 for(Enumeration keys = defaults.keys(); keys.hasMoreElements() ;) {
                         Object key = keys.nextElement();
                         System.out.println(key + ":\t\t " + defaults.get(key));
* </code>
