Help, I have been working on this for days

[ajimda]

I 'm new to java and taking a class. I have a problem for a savings account that adds deposits, withdrawals, calculates interest etc. I cannot get the monthlyInterestEarnedTotal to return. I had it working, but then it didn't. Can anyone tell me why and what I am doing wrong. Thank you..


public class SavingsAccountMain {

public static void main(String[] args) {

Scanner keyboard = new Scanner(System.in);

NumberFormat currency = NumberFormat.getCurrencyInstance();

double annualInterestRate = 0;
double beginningBalance;
double calcEndingBalance;


System.out.println("Enter the beginning balance amount of "
+ "your account: ");
beginningBalance = keyboard.nextDouble();

System.out.println("Enter the enter the annual interest you receive"
+ " on this this Account: ");
annualInterestRate = keyboard.nextDouble();

while (annualInterestRate < 0 || annualInterestRate > 1) {

System.out.println("Your number is Invalid.");
System.out.println("You must enter a positive deminal i.e. 5% = .05 ");
annualInterestRate = keyboard.nextDouble();
}


SavingsAccount money = new SavingsAccount(beginningBalance);

money.getCalcEndingBalance();


System.out.println("Your beginning balance was: " + currency.format(beginningBalance));

System.out.println("Your total withdrawals were: " + currency.format(money.getWithdrawalTotal()));

System.out.println("Your total deposits were: " + currency.format(money.getDepositTotal()));

System.out.println("Your total interest earned was: " + currency.format(money.getMonthlyInterestEarnedTota l()));

System.out.println("Your ending balance is: " + currency.format(money.getEndingBalance()));

}
}

When do you return it?

If you want help, you should provide an SSCCE that eliminates all the extra stuff and only demonstrates the problem. Also, don't forget the code tags.
