BJP3 Exercise 7.18: wordLengths

Added by: Whitaker Brand on 2013/04/01
Language: Java

Write a method called wordLengths that accepts a Scanner representing an input file as its argument. Your method should read from the given file, count the number of letters in each token in the file, and output a result diagram of how many words contain each number of letters. Use tabs before the asterisks so that they'll line up. If there are no words of a given length, omit that line from the output.

For example, if the file contains the following text:

Before sorting:
13 23 480 -18 75
hello how are you feeling today

After sorting:
-18 13 23 75 480
are feeling hello how today you

your method should produce the following output to the console:

2: 6    ******
3: 10   **********
5: 5    *****
6: 1    *
7: 2    **
8: 2    **

You may assume that no token in the file is more than 80 characters in length.
