    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).
