// Create tree
    JTree tree = new JTree();
    DefaultTreeModel model = (DefaultTreeModel)tree.getModel();
    
    // Find node to remove
    int startRow = 0;
    String prefix = "b";
    TreePath path = tree.getNextMatch(prefix, startRow, Position.Bias.Forward);
    MutableTreeNode node = (MutableTreeNode)path.getLastPathComponent();
    
    // Remove node; if node has descendants, all descendants are removed as well
    model.removeNodeFromParent(node);
    
    // The root cannot be removed with removeNodeFromParent();
    // use the following to remove the root
    model.setRoot(null);
