A. Create a program that allows a user to input customer records (ID number, first name, last name, and balance owed) and save each record to a file. Save the program as WriteCustomerList.java. When you execute the program, be sure to enter multiple records that have the same last name because you will search for repeated first names in part d of this exercise.

This is what I have so far. It does not write to the file it creates?

} }
