如何继续使用您在第一个变量中获得的值不再开始

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继续到另一个变量，而不是重新开始。帮帮我！

Answer 1

在此代码中

int fifty = (money % 100) / 50;

您可以计算money % 100并将其存储在变量中，您可以重复使用

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

还要注意整数除法

Answer 2

请在程序中进行一些小的修改。请看一次下面的代码。

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