目前在编译文件时出现错误问题
我一直在检查我的 while 循环和其他东西，看看问题出在哪里，但我找不到
这就像现在显示的唯一错误（我希望）
希望有人可以帮助解决我错过了哪个支架或它是什么类型的支架，因为我很困惑;_;

我当然错过了一些东西，但我不知道是哪一个
这些是我需要为我的输出显示的输入 txt 文件
它需要匹配顶部索引的长度（这就是我使用array.length的原因）
电力.txt
number of integers in file "electricity.txt" = 4
index = 0, element = 1877
index = 1, element = 1923
index = 2, element = 1879
index = 3, element = 20001000.txt
number of integers in file "1000.txt" = 1001
index = 0, element = 1000
index = 1, element = 2
index = 2, element = 3
index = 3, element = 5
index = 4, element = 7
index = 5, element = 11
index = 6, element = 13
index = 7, element = 17
index = 8, element = 19
till index 1000 and element 7919这是可以正常工作的代码，但在每个 txt 文件达到一定数量后会显示空值
