我正在学习 java atm ，不得不编写代码来计算货币单位，并且只使用单数词表示单个单位，使用复数词表示复数单位来显示非零面额。
这是目前的代码:
import java.util.Scanner;
public class ComputeChange {
public static void main(String[] args) {
Scanner input = new Scanner(System. in );
// receive amount
System.out.println("Enter an amount in double, for example 11.56: ");
double amount = input.nextDouble();
int remainingAmount = (int)(amount * 100);
// find the number of one dollars
int numberOfDollars = remainingAmount / 100;
remainingAmount = remainingAmount % 100;
// find the number of quarters in the remaing amount
int numberOfQuarters = remainingAmount / 25;
remainingAmount = remainingAmount % 25;
//find the number of dimes in the remaing amount
int numberOfDimes = remainingAmount / 10;
remainingAmount = remainingAmount % 10;
//find the number of nickels in the remaing amount
int numberOfNickles = remainingAmount / 5;
remainingAmount = remainingAmount % 5;
//find the number of pennies in the remaining amount
int numberOfPennies = remainingAmount;
//Display results
System.out.println("Your amount" + amount + "consists of");
if (numberOfDollars > 1) {
System.out.println(" " + numberOfDollars + "dollars");
} else if (numberOfDollars == 1); {
System.out.println(" " + numberOfDollars + "dollar");
}
输出是: 运行:
Enter an amount in double, for example 11.56:
12,33
Your amount12.33consists of
12dollars
12dollar
1quarters
1quarter
0dimes
0dime
1nickles
1nickle
3pennies
3penny
为什么所有内容都打印了两次？ 3 == 不是 1 那么为什么它仍然说 3 便士？ 也许是新手问题，但那是因为我是其中之一 :) 感谢您的帮助!
