The example introduce you how to use the JTree swing component to create a presentation of hierarchical data. The hierarchical data can be viewed in expand mode or collapse mode. To create an item of the tree we create an instance of DefaultMutableTreeNode which located in the javax.swing.tree package. This class implements the TreeNode and […]
