Compounding interest-Programm in Java

Ich versuche, dies zu schreiben, compounding interest-Programm mit einer do-while-Schleife am Ende und ich kann nicht herausfinden, wie drucken Sie die endgültige Höhe.

Hier ist der code, den ich bisher :

public static void main(String[] args) {
    double amount;
    double rate;
    double year;

    System.out.println("This program, with user input, computes interest.\n" +
    "It allows for multiple computations.\n" +
    "User will input initial cost, interest rate and number of years.");

    Scanner keyboard = new Scanner(System.in);

    System.out.println("What is the initial cost?");
    amount = keyboard.nextDouble();

    System.out.println("What is the interest rate?");
    rate = keyboard.nextDouble();
    rate = rate/100;

    System.out.println("How many years?");
    year = keyboard.nextInt();


    for (int x = 1; x < year; x++){
        amount = amount * Math.pow(1.0 + rate, year);
                }
    System.out.println("For " + year + " years an initial " + amount + " cost compounded at a rate of " + rate + " will grow to " + amount);


    String go = "n";
    do{
        System.out.println("Continue Y/N");
        go = keyboard.nextLine();
    }while (go.equals("Y") || go.equals("y"));
}

}
