Question

JAVA PROBLEM

Using the data provided, create print-out that will print a letter per customer (total of 1000 customers).

Every letter should be 66 lines in total

Each letter cannot exceed 80 columns.

Print the letter for only customer who has more than $5 balance.

It should print nicely.

You will need to calculate new amount due if not paid in 10 day. You need to calculate the new date (system date + 10 days).

Letter date is the system run date.

Deliverable:

Project folder as a zip file. Your output (ColLetter_yourInitials.txt) should be created at your project folder)

Place your input file in the same directory as this java file with name "input.txt". After running the program, you will get a folder as output, inside which all the files will be residing corresponding to letters for first_name.

Sample Output:

FirstNameDPT.txt:

ACME Inc.
123 Coffee Beans Street
Java, GA 99999

FirstNameDPT LastDPT
406 Main Street

Dear FirstNameDPT LastDPT,

Our records shows unpaid balance of $444.87 that is over 120+ days old.
The balance due is now. If the balance is not fully paid in ten days (by
3/27/2017), we will have to inform the collection agent for outstanding
balance plus %10 processing fee that increases total amount to $489.36.

If you have any questions or like to discuss a payment plan, please donot
hesitate our office at 555-555-5555.
