I'm using Eclipse and even though I've done more challenging things than this I keep getting stuck no matter how hard I hammer away at it.
This is a package, so the end of the first part (Driver Class?) is really what I'm having trouble with. Comments are included in the code. Also including the second part/ class is included.
Any guidance, help, flashing light bulbs would be greatly appreciated.
package 6;
import java.util.Scanner;
import java.text.DecimalFormat;
/**
* @author Me

*/
public class testAccount {
/**
* @param args
*/
public static void main(String[] args) {
String input;
double balance = 0, InterestRate = 0;
double interest, deposit, withdrawals;
double totalInterest=0, totalDeposits=0, totalWithdrawals=0;
int month=0;
char repeat='Y';
Scanner keyboard = new Scanner(System.in);
DecimalFormat degrees = new DecimalFormat("#,###.00");
System.out.println("What is your account's starting balance?");
balance= keyboard.nextDouble();
System.out.println("What is your annual interest rate?");
InterestRate= keyboard.nextDouble();
SavingsAccount account= new SavingsAccount (balance, InterestRate);
interest=account.MonthlyInterestRate(InterestRate);
balance=account.calculateInterest(balance);
//me testing to see If I can at least get the right balance but
///Something is wrong with my decimal formatter,
//keeps adding two 00's when I tested it
System.out.println("Your balance is is" +degrees.format(balance));
//How do I step into this Loop?
while ( repeat =='Y'|| repeat =='y');
{
month++;
System.out.println("What are your deposits?");
deposit=keyboard.nextDouble();
account.deposit(deposit);
System.out.println( "your deposits" +deposit);
System.out.println("balance" +balance);
System.out.println("What are your withdrawals?");
withdrawals=keyboard.nextDouble();
account.withdraw(withdrawals);
//Around here I'm supposed to be using the Accumulators to set keep count of
//totalwithdrawals,totaldeposits etc.
System.out.println("Calculate Month" + (month +1) + "Y/N .");
repeat=keyboard.nextLine().charAt(0);
}
System.exit(0);
}
}and this is what it links to
I'm pretty sure (92% at least)most of it is correct
