import javax.swing.*;

import javax.swing.event.*;

import java.util.Properties;

import javax.swing.JTree.*;



public class TreeRootHide{

  public static void main(String[] args) {

    JFrame frame = new JFrame("Root Hide of tree");

    Properties prop = System.getProperties();

    JTree tree = new JTree(prop);

    tree.setRootVisible(false);

    JScrollPane scroll = new JScrollPane(tree);

    frame.getContentPane().add(scroll, "Center");

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    frame.setSize(350,400);
