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:

  1. 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：

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

使用以下代码进行检查：

  1. String a = "ch-255-110.hr-165-1394.hd-180-1380.lg-280-110";
  2. 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:

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

Checked with this

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

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