添加数字 java 并通过输入 0 停止

Question

我想做一个加法，如果用户输入数字 0，他将所有数字相乘，程序停止。我一直在寻找并不断尝试，但我仍然无法弄清楚。

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;
            }
        }
    }
}

您需要将输入与 stop 进行比较，而不是总 number:

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;
     }
}

样本input/output:

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
