问题

以下是您要翻译的代码部分的内容：

Exception message:

java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0

Here is the line of code at the highest leve:

hairPart = look.split("hr")[1].split(".")[0];

Whole method:

public static String splitFigure(String look) {

    String shoesPart = "";

    if (look.toLowerCase().contains("hr"))
    {
        hairPart = look.split("hr")[1].split(".")[0];
    }

    if (look.toLowerCase().contains("hd"))
    {

So users on my game can have figure codes like ch-255-110.hr-165-1394.hd-180-1380.lg-280-110, I am trying to only fetch certain parts of this figure code, but I am getting an ArrayIndexOutOfBoundsException

Example of what I passed in:

ch-255-110.hr-165-1394.hd-180-1380.lg-280-110

答案1

得分: 1

尝试使用这个替代：

look.split("hr")[1].split("\\.")[0]

使用以下代码进行检查：

String a = "ch-255-110.hr-165-1394.hd-180-1380.lg-280-110";
System.out.println(a.split("hr")[1].split("\\.")[0]);

不确定为什么会发生这种情况，但我曾经遇到过类似的问题。

英文:

Try using this instead:

look.split("hr")[1].split("\\.")[0]

Checked with this

String a = "ch-255-110.hr-165-1394.hd-180-1380.lg-280-110";
System.out.println(a.split("hr")[1].split("\\.")[0]);

Not sure why it's happening but I once faced a similar problem.
