java - 如何继续使用第一个变量中获得的值而不重新开始

Question

import java.util.Scanner;

public class MoneyChange {

    public static void main(String[] args) {

        Scanner reader = new Scanner(System.in);
        System.out.print("Input an amount of money: ");

        double value = reader.nextDouble();
        int money = (int) value;

        int thousand = money / 1000;
        int fivehundred = money / 500;
        int hundred = money / 100;
        int fifty = (money % 100) / 50;
        int twenty = ((money % 100) % 50) / 20;
        int ten = (((money % 100) % 50) % 20) / 10;
        int five = ((((money % 100) % 50) % 20) % 10) / 5;
        int one = (((((money % 100) % 50) % 20) % 10) % 5) / 1;

        System.out.println("Number of 1000-Bhat Banknote(s) is " + thousand);
        System.out.println("Number of 500-Bhat Banknote(s) is " + fivehundred);
        System.out.println("Number of 100-Bhat Banknote(s) is " + hundred);
        System.out.println("Number of 50-Bhat Banknote(s) is " + fifty);               
        System.out.println("Number of 20-Bhat Banknote(s) is " + twenty);
        System.out.println("Number of 10-Bhat Coin(s) is " + ten);
        System.out.println("Number of 5-Bhat Coin(s) is " + five);
        System.out.println("Number of 1-Bhat Coin(s) is " + one);

        reader.close();
    }
}

我想知道如何将第一个变量的值延续到另一个变量而不是重新开始。帮帮我吧!

Answer 1

在此代码中

int fifty = (money % 100) / 50;

您可以计算金钱% 100并将其存储在可以重复使用的变量中

int hun = money % 100;
int fifty = (hun) / 50;

另请注意Integer division
