Java - 将用户输入分配给变量/更改计数器 [英] Java - Assigning User Input to Variable / Change Counter

问题描述

我对java很新，虽然我对C ++有相当基本的了解。
对于我的任务，我正在计算变化并将其分类为美国货币（即，如果你有105美分，则将其分为1美元和1美分）。

逻辑上我理解如何这样做，但我在理解java语法方面遇到了一些麻烦。我很难找到一种方法将用户输入的值分配给我的创建变量。在C ++中你只需要使用cin，但Java在这方面似乎要复杂得多。

I'm quite new to java, although I have a fairly basic knowledge of C++. For my assignment I am counting change and sorting it into American currency (i.e., if you had 105 cents, it would divide it into one dollar and one dime).
Logically I understand how to do this, but I'm having some serious trouble understanding the java syntax. I'm having serious trouble to find a way to assign a user-inputted value to a variable of my creation. In C++ you would simply use cin, but Java seems to be a lot more complicated in this regard.

这是我到目前为止的代码：

Here is my code so far:

package coinCounter;
import KeyboardPackage.Keyboard;
import java.util.Scanner;


public class  helloworld
{

    public static void main(String[] args) 
    {   
        Scanner input new Scanner(System.in);
        //entire value of money, to be split into dollars, quarters, etc.
        int money = input.nextInt();
        int dollars = 0, quarters = 0, dimes = 0, nickels = 0;

        //asks for the amount of money
        System.out.println("Enter the amount of money in cents.");


        //checking for dollars, and leaving the change
        if(money >= 100)
        {
            dollars = money / 100;
            money = money % 100;
        }

        //taking the remainder, and sorting it into dimes, nickels, and pennies
        else if(money > 0)
        {
            quarters = money / 25;
            money = money % 25;
            dimes = money / 10;
            money = money % 10;
            nickels = money / 5;
            money = money % 5;
        }

        //result
        System.out.println("Dollars: " + dollars + ", Quarters: " + quarters + ", Dimes: " + dimes + ", Nickels: " + nickels + ", Pennies: " + money);

    }

}

我真的会感谢有关如何将用户输入分配给我的变量Money的一些帮助。但是，如果您在代码中看到另一个错误，请随时指出。

I would really appreciate some help with how to assign a user-input to my variable, Money. However, if you see another error in the code, feel free to point it out.

我知道这是非常基本的东西，所以我感谢您的所有合作。

I know this is really basic stuff, so I appreciate all of your cooperation.

推荐答案

更改此行：

Scanner input new Scanner(System.in);

收件人：

Scanner input = new Scanner(System.in);

这应该在以下行之后而不是之前：

And this should be after line below not before:

System.out.println("Enter the amount of money in cents.");

正如您所做的那样，下面的行将从输入 int value并将其分配给您的可变货币：

And as you did , the line below will read from input int value and assign it to your variable money :

int money = input.nextInt();
