Java Help, Running totals not working?
can someone tell me what is wrong with my code? when the loan amortization table prints, it doesn't keep a running total of the interest paid, and for some reason it makes the user pay one more payment than they should. thanks... here is my code: /* A program that creates a loan amortization table using the values for Initial Loan Principal, Annual Percentage Rate, and Monthly Payment supplied by the user. Rebecca Created using jGrasp CS 1337 */ import java.util.Scanner; //needed to accept information from the user import java.text.DecimalFormat; //needed to format the decimals public class AmortizationTable { public static void main (String[] args) { Scanner keyboard = new Scanner (System.in); //Create Scanner System.out.println("Welcome to the Loan Payment Calculator.\n"); //Get loan amount from the user System.out.print("Please enter the Initial Loan Principal: "); double initialAmt = keyboard.nextDouble(); //Get the interest rate from the user System.out.print("Please enter the Annual Percentage Rate: "); double APR = keyboard.nextDouble(); //Get the payment amount from the user System.out.print("Please enter the Monthly Payment Amount: "); double monthPmt = keyboard.nextDouble(); System.out.print("Month\tPayment\t\tInterest\tPrincipal Paid\t"); System.out.println("Remaining Principal\tTotal Interest Paid"); int month = 0; int pmtNumber = 0; double remPrinc; do { DecimalFormat formatter = new DecimalFormat("0.00"); remPrinc = initialAmt - (monthPmt * pmtNumber++); double intrst = (remPrinc * (APR/100)) / 12; double intPdSoFar =+ intrst; double principal =+ (monthPmt - intrst); double princ =+ principal; System.out.print(month++); System.out.print("\t\t"); System.out.print(formatter.format(monthPmt)); System.out.print("\t\t"); System.out.print(formatter.format(intrst)); System.out.print("\t\t"); System.out.print(formatter.format(princ)); System.out.print("\t\t"); System.out.print(formatter.format(remPrinc)); System.out.print("\t\t\t"); System.out.println(formatter.format(intPdSoFar)); }while (remPrinc > 0); } }

java help, running totals?
something is wrong with my code... my interest paid will not keep a running total. declaring my variables outside of the do-while loop has caused it to run forever. please help, this is my code: /* A program that creates a loan amortization table using the values for Initial Loan Principal, Annual Percentage Rate, and Monthly Payment supplied by the user.
