okay basically im a new java programmer and am trying to make a simple
bank account typish program... one that you can deposit and withdraw
and all and the balance will be read from/writen to a file, so that it
can be a permanent use. I use JCreator and compile/run directly in the
program. Here is my code:

import static java.lang.System.out;
import java.util.Scanner;
import java.io.*;

class bank {

    public static void main (String args []) throws IOException {
        Scanner inputScanner = new Scanner(System.in);
        Scanner balanceScanner = new Scanner(new File("C:\\Documents and
Settings\\Caleb\\My Documents\\java\\balance.txt"));
        double balance = balanceScanner.nextDouble();

        out.println("Your account balance is $" + balance);
        out.println("Would you like to make a deposit or withdrawal?");
        out.println("d=deposit, w=withdrawal");
        String action = inputScanner.next();

        if (action.equals("d")) {
            out.println("How much would you like to deposit?");
            double depositAmount = inputScanner.nextDouble();
            balance = balance + depositAmount;
            out.println("Your balance is now $" + balance);

           FileWriter out = new FileWriter("C:\\Documents and
Settings\\Caleb\\My Documents\\java\\balance.txt");
           out.write(balance);
           out.close();
        } if (action.equals("w")) {
            out.println("How much would you like to withdraw?");
            double withdrawalAmount = inputScanner.nextDouble();
            balance = balance - withdrawalAmount;
            out.println("Your balance is now $" + balance);

        }

    }
}

The error message it shows is: "Cannot find symbol method
write(double), line 24, which is out.write(balance);... and i dont have
any clue how to fix it so that the double variable "balance" will be
written back to that file
