Write a program that allows the user to specify a filename on the command line. If the filename is not specified, the program prompts the user for the filename. The program then prints the number of characters, words, and lines in that file. Use a class with a constructor that takes a File object and methods to get the line count, word count, and character count.

Example:

Enter Filename: BabyNames.txt BabyNames.txt 101 500 2999
