The tree is composed of nodes, in Java, uses the DefaultMutableTreenode class to create nodes. The process of creation is simple. First create a root node, then create a child of the root node, let the child node add your child node to the parent node after adding the Add (MutableTreenodenewChild) method.
// Create a node DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode ( "Java"); DefaultMutableTreeNode books = new DefaultMutableTreeNode ( "Java books"); DefaultMutableTreeNode tools = new DefaultMutableTreeNode ( "Java Development Tools");
// Add a child node rootnode.add (booS); rootnode.add (tools);
Books.Add (New DefaultMutableTreenode); Books.Add (New DefaultMutableTreenode ("Java Programming Thought")); Books.Add (New DefaultmutableTreenode ("Java Programming Detailed");
Tools.Add (New DefaultmutableTreenode ("jbuilder"); Tools.Add (New DefaultmutableTreenode ("jcreat")); Tools.Add (New DefaultmutableTreenode); "Visual J ));
