Description of program:

You are to write a program that will prompt the user for an input file name to read from. The Input file will consist of records made up of first name, last name and an account balance of individuals and store the individuals in an ArrayList. Each line in the file would be made up of one record starting with the last name, first name and account balance. Each token is separated by ONE space. The individuals names' must be inserted in sorted order into the list - sort by last name and then first name.

The program must be named "" .

10. Display the contents from the list to the screen and into an output file - "output.txt".

11. Count the amount of individuals in the list and display the value on the screen and the output file.DO NOT USE ANY LIBRARY FUNCTION TO COUNT. YOU MUST WRITE YOUR OWN COUNTING FUNCTION.
