用java编写一个程序，读取用户输入的货币金额，然后确定代表该金额所需的每种纸币和硬币的最少数量，使用整除法

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("请输入货币金额：");
double amount = scanner.nextDouble();

int dollars = (int) amount;
int cents = (int) ((amount - dollars) * 100);

int twentys = dollars / 20;
dollars = dollars % 20;

int tens = dollars / 10;
dollars = dollars % 10;

int fives = dollars / 5;
dollars = dollars % 5;

int ones = dollars;

int quarters = cents / 25;
cents = cents % 25;

int dimes = cents / 10;
cents = cents % 10;

int nickels = cents / 5;
cents = cents % 5;

int pennies = cents;

System.out.println("最少的零钱数量为：");
System.out.println("纸币：");
System.out.println("20元纸币：" + twentys);
System.out.println("10元纸币：" + tens);
System.out.println("5元纸币：" + fives);
System.out.println("1元纸币：" + ones);
System.out.println("硬币：");
System.out.println("25美分硬币：" + quarters);
System.out.println("10美分硬币：" + dimes);
System.out.println("5美分硬币：" + nickels);
System.out.println("1美分硬币：" + pennies);
}
}
