我不知道是什么原因造成的，我想我将打开一个单独的更集中的问题

I don't know what's causing this, I guess I will open a separate more focused question

推荐答案

Access element at 0th index，因为您的数组大小为1表示它在第0个索引位置包含单个元素

Access element at 0th index because your array size is 1 means it contain single element at 0th index position

java.lang.IndexOutOfBoundsException的原因是您的数组仅包含一个元素.它在位置索引0而不是位置1.您正在访问索引1处的元素，这是不可能的.

java.lang.IndexOutOfBoundsException is thrown because your array contain only one element. It's at location index 0 not at 1. you are accessing element at index 1 which is not possible.

仅尝试访问0索引不要超过0.

Try to access 0 index only don't go for more than 0.
