java - Java更改计算器输出

我正在编写一个代码，该代码将从标准输入中读取一个实数为两倍，然后获取该值并打印出最少的纸币和硬币以达到该数量。我不确定如何在必要时将代码打印成一定数量的代码。如果有人可以鸣叫，我将不胜感激！

import java.util.Scanner;
import java.lang.Math;
public class Changecalc {
public static void main(String[] args) {
     Scanner input = new Scanner(System.in);
     System.out.println("Enter amount) ");
     double amount = input.nextDouble();
     int amountInt = (int) (amount * 100);

     double tmp;
     if(amount >= 100)
         {
         tmp = (int) amount/100;
         System.out.println (tmp + "$100 bills");
         amount = amount % 100;
         }
     if(amount >= 50)
         {
         tmp = (int) amount/50;
         System.out.println (tmp + "$50 bills");
         amount = amount % 50;
         }
    if(amount >= 20)
    {
        tmp = (int) amount/50;
        System.out.println (tmp + "$20 bills");
        amount = amount % 20;
    }
    if(amount >= 10)
    {
        tmp= (int) amount/50;
        System.out.println (tmp + "$10 bills");
        amount = amount % 10;
    }
    if(amount >= 5)
    {
        tmp = (int) amount/5;
        System.out.println (tmp + "$5 bills");
        amount = amount % 5;
    }
    if(amount >= 1)
    {
        tmp = (int) amount/1;
        System.out.println (tmp + "$1 bills");
        amount = amount % 1;
    }
    if(amount >= .25)
    {
        tmp = (int) amount/.25;
        System.out.println (tmp + "quater");
        amount = amount % .25;
    }
    if(amount >= .10)
    {
        tmp = (int) amount/.10;
        System.out.println (tmp + "dime");
        amount = amount % .10;
    }
    if(amount >= .05)
    {
        tmp = (int) amount/.05;
        System.out.println (tmp + "nickel");
        amount = amount % .05;
    }
    if(amount >= .01)
    {
        tmp = (int) amount/.01;
        System.out.println (tmp + "penny");
        amount = amount % 01;
    }
}
}

最佳答案

您的代码大部分是正确的。只是当金额> = 20时，

if(amount >= 20)
{
    tmp = (int) amount/50;
    System.out.println (tmp + "$20 bills");
    amount = amount % 20;
}

  相反，它应该是

if(amount >= 20)
{
    tmp = (int) amount/20;
    System.out.println (tmp + "$20 bills");
    amount = amount % 20;
}

  类似的问题是当金额> = 10时。您需要将其更正为
  好。


除此之外，您还需要具有打印一张或多张钞票的逻辑（如果有多个钞票），并且对四分之一硬币，一角硬币，镍币和便士/小笔有类似的逻辑




  对于复数，您可以使用类似于以下内容

if(amount >= 100){
     tmp = (int) amount/100;
     if(tmp > 1.0){
         System.out.println (tmp + "$100 bills");
     } else{
         System.out.println (tmp + "$100 bill");
     }
     amount = amount % 100;
 }
