a Java program that reads in the following values from the standard input device (i.e.
KeyboaRD) and writes its result on the standard output device (i.e. Console/Monitor):
Inputs:
A: the loan amount in dollars and cents (e.g. 150000.00).
r: the net annual interest rate, expressed as an integer (e.g. 10 which means 10％)
Y: the number of whole remaining years (for repayment)
M: the number of remaining months
Output:
The program should calculate and output the amount of monthly repayments in dollars and cents as
single value (e.g. $840.55)
* The KeyboaRD is assumed to be a matrix having 4 rows by 6 columns. However, this code works for any
* matrix arrangements up to an 8 x 8 matrix. By using from one to three of the column inputs, the driver
* can support "SHIFT" keys. These keys are: SHIFT1, SHIFT2 and SHIFT3.
