In this section, you will learn to make JTree editable nodes. For example. . If you want to edit the name of a tree node then the following program will help you a lot.
This program constructs a JTree that contains editable nodes. Firstly, it defines a class "JTreeEditable". Here we have used the init() method to create the nodes (Root, open, close, save, save as, and exit) of the tree. These nodes are added in a JTree object and we set the editable mode to " true " through the setEditable() method. The init() method adds these components to the JFrame. When you want to edit these components, just double click them and rename them..
This method takes a boolean value that is either a 'true' or a 'false'. When you enter true it becomes editable.
Here is the code of this program:
