如何将钱兑换成零钱

尝试将输入的数字转换为 25 美分、50 美分、10 美分和 10 分。有几个问题：

    public class Coins {
public static void main(String[] args){

private int quarters, dimes, nickels, pennies;

public void CoinsToChange(TotalCoins){
    quarters = (int)(TotalCoins/25);
    TotalCoins %= 25;
    dimes = (int)(TotalCoins/10);
    TotalCoins %= 10;
    nickels = (int)(TotalCoins/5);
    TotalCoins %= 5;
    pennies = (int)(TotalCoins/1);
    TotalCoins %= 1;

    System.out.println("Quarters = " + quarters + "\nDimes = " + dimes + "\nNickels = " + nickels + "\nPennies = " + pennies);
    }
}
    }

这是我的测试器类：（我在调用 CoinsTotChange 方法时遇到问题。）

     import java.util.Scanner;

    public class CoinsTester {
    Coins money = new Coins();
    money.CoinsToChange(changeMoney);
    Scanner kybd = new Scanner(System.in);
    int changeMoney = kybd.nextInt();

}

尝试改变操作顺序。在声明/实例化之前，您通常不能使用对象/变量。

Coins money = new Coins();
Scanner kybd = new Scanner(System.in);
int changeMoney = kybd.nextInt();
money.CoinsToChange(changeMoney);
