java字符串转换

Question

我写了下面的java代码。抛出数组索引超出范围异常

Exceptions: exception_name = java.lang.ArrayIndexOutOfBoundsException 
    exception_message = Array index out of range: 1

这个问题能不能解决？

public class UnifiedClus1toNfastfastsamehost extends UnifiedClus1toNfastfastsamehostHelper
{
    /**

Answer 1

不幸的是，您的异常没有显示源文件或行号，这让我们猜测。

我在显示的代码中看不到下标1的任何用法，所以问题可能出在某个被调用的方法中。

if (options.toLowerCase().contains("Failover"))

包含一个错误，但是:一旦你小写options，结果字符串将不会像在"Failover"中那样包含大写的"F“！

Answer 2

检查在调用testMain(Object[] args)时，参数"args“不应该为空。最好在方法本身中放入一个空检查

字符串选项= ""；if (args!=null){ options = options+ args；}
