public void mouseClicked(MouseEvent e) {
          int x = e.getX();
          int y = e.getY();
          int row = tree.getRowForLocation(x, y);
          TreePath path = tree.getPathForRow(row);
          if (path != null) {
            CheckBoxNode node = (CheckBoxNode) path.getLastPathComponent();
            boolean isSelected = ! (node.isSelected());
            node.setSelected(isSelected);
            if (node.getSelectionMode() == CheckBoxNode.DIG_IN_SELECTION) {
              if (isSelected) {
                tree.expandPath(path);
              }
              else {
                tree.collapsePath(path);
              }
            }
            ( (DefaultTreeModel) tree.getModel()).nodeChanged(node);
            if (row == 0) {
              tree.revalidate();
              tree.repaint();
            }
          }
          if (rightTree == e.getSource()) {
            try {
              hashTable = new Hashtable();
              CheckBoxNode selectedNode = (CheckBoxNode) rightTree.
                  getLastSelectedPathComponent();
              CheckBoxNode parentNode = (CheckBoxNode) selectedNode.getParent();
    
              if (selectedNode.isLeaf()) {
                Enumeration enum = parentNode.children();
                value = new String[parentNode.getChildCount()];
                while (enum.hasMoreElements()) {
                  for (int j = 0; j < value.length; j++) {
                    value[j] = (parentNode.toString() + "  " +
                                String.valueOf( ( (CheckBoxNode) enum.nextElement()).
                                               isSelected));
                  }
                }
                hashTable.put(key, value);
    
                Iterator iterator = hashTable.keySet().iterator();
                String[] getValue;
                while (iterator.hasNext()) {
                  String s = (String) iterator.next();
                  System.out.println("key " + s);
                  getValue = (String[]) (hashTable.get(s));
    
                  for (int i = 0; i < getValue.length; i++) {
                    System.out.print("  value " + "  " + value[i]);
                  }
                }
              }
            }
            catch (Exception exception) {
              exception.printStackTrace();
            }
          }
        }    }

Answer 3
