新人关于Java Ping IP 的程序遇到的问题，求各路大神解答

[StarMoonStorm]

这个程序是设想在JtextArea上输入ip还有读取xls文件可以获取ip，然后循环处理批量的ip输出结果，而且可以保存。
现在的问题有：一，单ip输入到jtextarea之后可以判断出是否ping通，但多ip就出现两个ip都在一个数组；二，打开xls
文件之后ping出来的结果全是ping通，其中有一个不通的ip也显示ping通

我会在二楼放上程序代码。

控制台错误信息如下：

这里说的很清楚 Line-174 越界

引用 2 楼 aschouas 的回复:

这里说的很清楚 Line-174 越界

所以是怎么搞 Line 174是指 ipresult = ipAddress[i] + "\t" + "通" + "\r\n"; 代码里面的第178行
