My output display this: [email protected]

The output should display Years: 30, Loan Amount $200000.00, Interest Rate: .0575, and Monthly Payment: Calculated by Math.POW. Then a list of loan balance and interest paid for each payment over the term of the loan should scroll off the screen, but need loops to display a partial list, hesitate and then display more of the list. Do not use a graphical user interface. Please insert comments in the program so I can understand the fixes.

The setter and getters must stay in MortgageCalculator.java and everything should output from main (Driver.java).

* 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% in class driver.java
* Algorithm - standard loan calculation with fixed number of payments:
* Monthly Payment = Principal * (InterestRate / (1 - (InterestRate + 1) - 12 * Periods)

* Inputs:
* Principal = $200,000
* Interest Rate = 0.0575
* Periods = 360
