Question

NEED HELP! The program must read the data from the input file and then output the amortization reports in a scrolling pane in a window. Write this program by breaking up the problem into smaller methods. The program cannot be written so all the work is done in the main method. Define at least 2 other method definitions (to break up the work into smaller chunks).

The input file is a file of records with customer information. Each record contains the homeowner's name, address, city, state, and zip code. It also includes the month, day, and year the loan was made, the total amount borrowed, the annual percentage rate at which the money was lent, and a number indicating the payment amount.

Copy the text below into notepad to save as a .txt file. Name that file "fcrc loan data.txt" This will be the import file. Place the text file into the root directory of the program.

"Bill Olsen" "914 8th Street" "Salt Lake City" UT 84112 2 25 2012 1250.00 .0325 2

"Mary Henderson" "1374 Oak Lane" "Love Canal" NY 10035 3 28 2012 7000.00 .0625 3

"Austin Powers" "10 Downing St." "Pittsburg" PA 13417 4 1 2012 12800.00 .0700 5
