Question

我正在尝试为此编写算法：有100名学生和100个储物柜。第一个学生从第一个储物柜开始，每个人打开。下一个学生，学生二，从第二个储物柜开始，如果它打开则关闭每个第二个储物柜，反之亦然。第三个学生从第三个储物柜开始，每三个储物柜重复一次。我写了一些我认为应该可以工作的东西，但是我的阵列已经超出了界限，我不知道如何：

public static void main(String[] args) 
{
    int startingStudents = 1;
    int lockersToCheck = 1;
    int lockersPosition = 1;
    boolean[] lockers = new boolean[101];

    //Cycles through 100 students
    for(int students = startingStudents; startingStudents <= 100; students++)
    {
        //What each student does
        while(lockersToCheck <= 100)
        {
                            //If its closed, open
            if(lockers[lockersToCheck] == false)
            {
                lockers[lockersToCheck] = true;
            }
                            //If its open, close
            else
            {
                lockers[lockersToCheck] = false;
            }

                            //Which locker they should be at
            lockersToCheck += lockersPosition;
        }


        //Zero out to start at the right locker
        lockersToCheck = 0;
                    //Where the next student starts
        lockersPosition += students;
                    //Make sure the next student starts there
        lockersToCheck = lockersPosition;

    }

    for(int n = 1; n <= 100; n++)
    {
        System.out.print(lockers[n] + " " + n);
    }

}

感谢您的帮助！

Answer 1

for（int students = startingStudents; startingStudents ＆lt; = 100; students ++）

应该是

for（int students = startingStudents; students ＆lt; = 100; students ++）

Answer 2

这是你的循环终止

for(int students = startingStudents; startingStudents <= 100; students++)

应该是

for(int students = 1; students <= 100; students++)

因此，我猜你没有得到一个ArrayIndexOutOfBoundsException，而是一个Heap-Space-Exception。

我的阵列在哪里出界？
