问题

我想进行加法运算，如果用户输入数字0，则将所有数字相乘，程序停止运行。我已经进行了搜索并不断尝试，但仍然无法弄清楚。

```java
import java.util.Scanner;

public class counting {
    public static void main (String[] args) {
        int number = 0, stop = 0;

        Scanner kb = new Scanner (System.in);
        while(true) {
            System.out.print("请输入一个数字（输入0停止）：");
            number += kb.nextInt();

            if (number == stop) {
                System.out.println("所有数字的乘积：" + number);
                return;
            }
        }
    }
}

I want to make an addition and if the user enters the digit 0 he multiplies all numbers together and the program stops. I&#39;ve already been searching and keep trying, but I still can&#39;t figure it out.

import java.util.Scanner;

public class counting {
public static void main (String[] args) {
int number = 0, stop = 0;

    Scanner kb = new Scanner (System.in);
    while(true) {
        System.out.print("Enter a number (stop with 0): ");
        number += kb.nextInt();

        if (number == stop) {
            System.out.println("Outcome of the numbers " + number);
            return;
        }
    }
}

}

你需要将输入与 ``stop`` 进行比较，而不是与总 ``number`` 进行比较：
```java
int number = 0, stop = 0;

Scanner kb = new Scanner(System.in);
while (true) {
    System.out.print("输入一个数字（输入 0 停止）：");
    int input = kb.nextInt();
    number += input;
    if (input == stop) {
        System.out.println("数字的总和为 " + number);
        return;
    }
}

示例输入/输出：

输入一个数字（输入 0 停止）：1
输入一个数字（输入 0 停止）：2
输入一个数字（输入 0 停止）：3
输入一个数字（输入 0 停止）：0
数字的总和为 6

int number = 0, stop = 0;

Scanner kb = new Scanner (System.in);
while(true) {
     System.out.print("Enter a number (stop with 0): ");
     int input = kb.nextInt();
     number += input;
     if (input == stop) {
          System.out.println("Outcome of the numbers " + number);
          return;
     }
}

Enter a number (stop with 0): 1
Enter a number (stop with 0): 2
Enter a number (stop with 0): 3
Enter a number (stop with 0): 0
Outcome of the numbers 6
