: Change the if statement into a while loop
:
:
if (amount > 0) //run if counter >0
:
: should look like:
:
:
while(amount > 0)

: : Hello,
: : Can anyone advise me on why I can't get the following code to loop? I'm trying to get continuous calculation until the variable amount = 0.
: : I will work out display params after I get the loop to work. I'm new to Java, but not coding. This is a simple program so there's probably a simple answer.
: : My thanks to anyone willing to teach me.
: : Thanks

: : import java.text.*;

: : class Wk3
: : {
: : public static void main (String[] arguments) //create main
: : {
: : int term = 30; //init var for length of loan
: : double amount = 200000; //init var for loan amt
: : double pmt = 0; //init var for payment
: : double rate = .0575; //init var for interest rate
: : double rateMo = 0; //init var for monthly interest paid
: : {
: : rate = (rate/12); //divide annual rate to get monthly rate
: : term = (term * 12); //multiply years to get length in months
: : pmt= (amount * (rate)) / (1-Math.pow(1 + rate, - term)); //compute payment
: : {
: : if (amount > 0) //run if counter >0
: : {
: : java.text.DecimalFormat dec = new java.text.DecimalFormat(",###.00"); //format next output to dollars.cents
: : System.out.println("\nThis months payment is $" + dec.format (pmt)); //display payment
: : System.out.println ("\nYour loan balance is $" + dec.format (amount)); //display loan amt
: : System.out.println("\nThis months interest is $" + dec.format (amount * (rate ))); //montly interest payment
: : }
: : amount -= pmt;
: : }
: : }
: : }
: : }

:
That would be an infinite loop as this line: amount -= pmt; is outside the if block
