推荐答案

java.lang.ArrayIndexOutOfBoundsException 表示您正在尝试访问不存在的数组索引.

java.lang.ArrayIndexOutOfBoundsException means you are trying to access a array index that doesn't exist.

问题是您的数组大小为 1.但是，您将执行该循环六次.您可以使 n 等于 1，也可以增加数组的大小.

The problem is that your array is of size one.However, you are going through that loop six times. You can either make n equal to one, or increase the size of your array.
