Java Chapter 22 Problem 6 - Binary Tree Input and Display

Please only use material relevant to the chapter.

You are given a file that contains data describing a binary tree whose nodes are strings. The file begins with an integer N, the number of nodes in the tree, on a line by itself. This first line is followed by N additional lines where each line specifies child information for a node in the tree. The line for a node X starts with X itself followed by a list of the children of X. Names of nodes are separated by whitespace.

For example, the data set:

5

Al Bob Carol

Bob Debby Elaine

Carol

Debby

Elaine

represents a binary tree in which Al has two children named Bob and Carol; Bob has two children named Debby and Elaine; and Carol, Debby, and Elaine have no children. Write a program that reads in data from such a file and displays it in a JTree component
