 * Created on June 27, 2004, 5:07 PM
 * Java Programming Project Workshop 2 –
 * Problem statement – Create a Mortgage Calculator WITHOUT a graphical user interface
 * Purpose – provide a user-friendly service to potential users for accurately planning mortgage and other types of loans
 * Scope – The mortgage calculator must display the mortgage payment amount given the amount of the mortgage, the term of the mortgage, and the interest rate of the mortgage. This program must have hard code amount = 200,000, term= 30 years, and the interest rate = 5.75%. .
 * Algorithm – standard loan calculation with fixed number of payments:
 * Monthly Payment = Principal * (InterestRate / (1 – (InterestRate + 1) – 12 * Periods) will be used for next workshop project
 *
 * Inputs:
 * Principal = $200,000
 * Interest Rate = 0.0575
 * Periods = 360
 *
 * Output:
 * Monthly Payment = $1167
