e1019. Creating a JTree Component

This example creates a tree component with a root node and a child of the root node. You build the tree hierarchy by adding nodes to nodes.

    DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root Label");
    root.add(new DefaultMutableTreeNode("Node Label"));
    
    JTree tree = new JTree(root);
