From source file:Main.java

public static void expand(JTree tree, int level) {
    DefaultMutableTreeNode currentNode = (DefaultMutableTreeNode) tree.getModel().getRoot();
    while (currentNode != null) {
        if (currentNode.getLevel() <= level) {
            tree.expandPath(new TreePath(currentNode.getPath()));
        }/* w  w w  .  j  a v a2s .com*/
        currentNode = currentNode.getNextNode();
    }
