java - 结果我不断得到0

这是针对一个学校项目的，我应该生成一个计算总金额的程序。结果我一直得到0。我做错什么了？谢谢！

package com.david.scanner;
import java.util.Scanner;

public class coin {
    public static void main (String[] Args){

        int quarters = 0;
        int dimes = 0;
        int nickels = 0;
        int pennies = 0;
        int totalCents = 0;
        int dollars = 0;
        int cents = 0;

        totalCents = (quarters*25 + dimes*10 + nickels*5 + pennies);
        dollars = (totalCents/100);
        cents = (totalCents%100);

        @SuppressWarnings("resource")
        Scanner keyboard = new Scanner(System.in);
        System.out.print("How many quarters do you have -->");
        quarters = keyboard.nextInt();
        System.out.println("How many dimes do you have -->");
        dimes = keyboard.nextInt();
        System.out.println("How many nickels do you have -->");
        nickels = keyboard.nextInt();
        System.out.println("How many pennies do you have -->");
        pennies = keyboard.nextInt();

        System.out.println("Quarters = " + quarters);
        System.out.println("Dimes = " + dimes);
        System.out.println("Nickels = " + nickels);
        System.out.println("Pennies = " + pennies);
        System.out.println("Total value =" + dollars + "dollars " + cents + "cents!");

    }
}

最佳答案

在获得实际值之前，您已经进行了计算。移动

totalCents = (quarters*25 + dimes*10 + nickels*5 + pennies);
dollars = (totalCents/100);
cents = (totalCents%100);

在接受输入并通过quarters分配pennies之后，但在最终输出之前。
