Java类把零钱分解成硬币？

Question

我正在做一个java分配，在那里你输入一个对象的价格和一个理论客户交给你的物品的金额。然后程序返回你欠他们的钱，并将其分解为你应该给他们的美元、二十五美分、一角美分、五美分和便士。

import java.util.*;
public class ChangeTendered {

    public static void main(String[] args){

        Scanner scan = new Scanner(System.in);

        System.out.println("Enter the purchase price: ");
        double price = scan.nextDouble();
        System.out.println("Enter the amount payed: ");
        double ammountPayed = scan.nextDouble();

        double changeDue = ammountPayed - price;

        int dollars = (int)changeDue;

        System.out.println("Return"+ dollars+ "Dollars");

        scan.close();
    }

}

Answer 1

下面是一个初步的方法

    int change = (int)(Math.ceil(changeDue*100));
    int dollars = Math.round((int)change/100);
    change=change%100;
    int quarters = Math.round((int)change/25);
    change=change%25;
    int dimes = Math.round((int)change/10);
    change=change%10;
    int nickels = Math.round((int)change/5);
    change=change%5;
    int pennies = Math.round((int)change/1);

    System.out.println("Dollars: " + dollars);
    System.out.println("Quarters: " + quarters);
    System.out.println("Dimes: " + dimes);
    System.out.println("Nickels: " + nickels);
    System.out.println("Pennies: " + pennies);

您还可以添加更多代码到为钞票做这件事。
