Java Programing

 I am trying to modify this mortage program I wrote to display 3
mortgage loans for 7 years ar 5.35%, 15 years at 5.5% and 30 years at
5.75% by using an array for the different loan and displaying the
mortage payment for each loan. These are suppose to loop. Need help
here is my program I worte: I canot get it to loop.

            DecimalFormat moneyFormat = new DecimalFormat(
"$###,###.00" );

//Calculate loan payment based on formula described in header
            loanPayment = loanPrincipal*((loanMonthlyRate) / (1 -
Math.pow(1 + loanMonthlyRate,-1 * loanPeriods)));

//Print basic summary output
