我的Excel工作表只有两列。用户自己添加y，第三个用于检查其他两列是否有效地插入到他的数据库中。 在尝试检查好几行的处理之后，我试图在第三列中编写内容时，但是如果有更多行，则每一行的第三列结果都不正确...
我认为如果有人可以帮助，for循环中的问题将不胜感激。谢谢。
这是我的代码：-...

答案 0 :(得分：0)
我已经找到了错误，并已将其修复
一共有三个循环
1- for（POS20083 POS20083：pos20083List） 2- for（int i = 0; i <= pos20083List.size（）; i ++） 3- for（int j = 0; j <= sheet.getFirstRowNum（）; j ++）
因此，如果我们删除第一个在此处无用的数据，因为我们总是从excel工作表中获取数据，因此效果很好...
第三个人也一样，在我的任务中也不太有用...
所以我需要的只是this循环
for（int i = 0; i <= pos20083List.size（）; i ++）
我们可以用此行替换返回实际行数的pos20083list
int行= sheet.getPhisicalNumberofRows（）-1
非常感谢 Layne Bernardo 的努力
