From text file to tree structure view using jtree

From text file to tree structure view using jtree

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
