From text file to tree structure view using jtree

Question

I am using JTree to build folder tree structure(GUI), I can build it manually if I know proper file structure. I want to implement this structure reading structure specified in text file, which is dynamic. I am bit poor in coding recursion type problems. Please help me

If in text file structure is as shown below

label - level

root - 0 LivingBeings - 1 animals - 2 dog - 3 cat - 3 birds - 2 peacock - 3 crow - 3

I need a tree structure like as shown in image

Answer 1

You should consider implementing the TreeModel interface. As an example, FileTreeModel , cited here , works with either JTree , as shown here , or Outline , as shown here .

See also XMLTree , which reads nodes from an XML file, cited here .
