Java中的NZEC运行时错误 [英] NZEC runtime error in Java

问题描述

这是我的代码.请检查它在哪里给出运行时异常.我写了一段代码来解决这个问题.

This is my code. Please check it where it is giving runtime exception. I wrote a piece of code to solve this problem.

我不断收到 NZEC(运行时错误)，但我找不到代码的哪一部分会导致任何异常，因为它只涉及简单的算术计算(不应该被零除).

I keep getting NZEC(runtime error), but I can't find which part of the code can cause any Exception since it only involves simple arithmetic computation (there should be no chance of divided by zero).

代码的逻辑无关紧要，我只是想知道异常可能隐藏在哪里.

The logic of the code doesn't matter, and I just wonder where the exception could be hiding.

任何人都可以发现任何错误?谢谢.

Any one can spot any bug? Thanks.

                arr[i] = sc.nextInt();
            for (int i = 0; i < n; i++)
                sum += arr[i];
            if (sum % n == 0) //if divisible by n,print n
                System.out.println(n);
            else
                System.out.println(n - 1);

        }
    }
}

推荐答案

您很可能在程序中创建了过多的内存.您必须在 while 循环外创建 array(arr) 并在循环内操作它..

You are most probably creating too many memory in program. you must create array(arr) outside the while loop and manipulate it inside the loop..
