amount = Double.parseDouble(amountStr); //convert input String into double
iRate = Double.parseDouble(irateStr); //convert input string into double
years = Integer.parseInt(yearsStr); //convert input string into integer

monPay = (amount * iRate / 1200) /
( 1 - Math.pow( 1 / ( 1 + iRate / 1200), 12 * years)) ;//calculate monthly payment
totalPay = monPay * 12 * years;

DecimalFormat df = new DecimalFormat("0.00");
System.out.println(df.format(monPay));


JOptionPane.showMessageDialog(null,"your monthly payment is: " + monPay + "\n" +
"your total payment is: " + totalPay );
}
