Question

1. Write a Java program to read and build a binary tree from a file. The
binary tree is represented using a matrix with two columns: node and
parent. Each line in the file represents a pair (node parent). In the
following example, the first line 6 6 represents the root of the tree -
node 6. The second line 3 6 represents the first child of the root ? node
3. The second line 4 6 represents the second child of the root ? node 4.
The last line 2 3 represents the only child of the node 3 ? node 2.
eg
6 6
3 6
4 6
2 3

invincible_me, of the seven posts you have started here:
- two of them are cross posted;
- only one of them has a fairly decent subject title (the recursion thread) all other titles tell jack about your question;
- in each and every thread your received answers but you have only responded in one thread, ignoring the rest.
So why would anyone try to answer you? You don't respond back, and chances are, you already received an answer in a cross posted thread already. So, answering you is a waste of (my) time.
