Selecting JTree node to send values

Question

Hello all,
I tried to build a GUI using JTree, It should be send values (a1,s1) to another method in back-end if a node (test1) is selected. is it necessary to add a new class with setXX() and getXX()?
-Test
--test1 (int a1, String s1)
--test2 (int a2, String s2)
    private void createNodes(DefaultMutableTreeNode top) {
        DefaultMutableTreeNode category = null;
        category = new DefaultMutableTreeNode("Test");
        top.add(category);
        category.add(new DefaultMutableTreeNode("test1"));
        category.add(new DefaultMutableTreeNode("test2"));
        top.add(category);
    }Could anybody give me some suggestions? Thanks in advance

I use the following code to blocking input events:
      waitTimer = new Timer(350, new ActionListener() {
        public void actionPerformed(ActionEvent e) {
          Toolkit.getDefaultToolkit().addAWTEventListener(awtEventListener,
              AWTEvent.MOUSE_EVENT_MASK | AWTEvent.MOUSE_WHEEL_EVENT_MASK | AWTEvent.KEY_EVENT_MASK);
      waitTimer.setRepeats(false);
      waitTimer.start();The event listener looks like:
    awtEventListener = new AWTEventListener() {
      public void eventDispatched(AWTEvent anEvent) {
        if(anEvent instanceof InputEvent && anEvent.getSource() instanceof Component)  {
            ((InputEvent) anEvent).consume();
    };
