The Java platform provides extensive classes and interfaces for tree-related programming. Beside the JTree class in the javax.swing package, almost others reside in a separate package: javax.swing.tree.

Here are some noticeable classes and interfaces:

  • JTree: The component class that displays the tree.
  • TreeNode: This interface specifies the requirements that an object should implement to be used as a tree node. Java provides a default implementation class DefaultMutableTreeNode.
  • TreeModel: This interface defines the data model that is used by the JTree. The JTree displays the tree structure based on the model. TheDefaultTreeModel class is the default implementation provided by the Java platform.
  • TreeCellRenderer: An object must implement this interface to customize the display of a tree node. DefaultTreeCellRenderer is the default implementation.
  • TreeCellEditor: An object must implement this interface to handle edit action on a tree node.
  • TreeSelectionListener: Implement this interface to listen to selection changes on the tree.

you can run this code netbeans .
