Question

Write a static method named textCount that takes a Scanner representing a file as a parameter and that reports various statistics about the file. In particular, your method should report the number of lines in the file, the total number of characters (not counting any new-line characters) in the file, and the length and text of the longest line. You may assume that the input file has at least one line of input.

For example, if the file contains the following text:

Twas brillig and the slithy toves

did gyre and gimble in the wabe.

All mimsey were the borogroves,

and the mome raths outgrabe.

"Beware the Jabberwock, my son,

the jaws that bite, the claws that catch,

Beware the JubJub bird and shun

the frumious bandersnatch."

The program would find that there are 9 lines (blank lines count), a total of 254 characters in the file (33 on the first line, 32 on the next line, 31 on the next line, 28 on the next, 0 on the next, etc) and that the longest line is the one that begins with "the jaws that bite". The method would produce the following output:

Total lines            = 9

Total chars            = 254

Length of longest line = 41

Longest line           = the jaws that bite, the claws that catch,
