Basically this line of code does not work and I’m not quite sure as to why:

    String[] stringHolder = string.split("_(B");

I get this error: Unclosed group near index 3

This line of code works however:

    String[] stringHolder = string.split("_B");

So this leads me to believe that it’s caused by the “(“. Can anyone tell me how to make this work?

The ( is a special character in regex, you need to escape it with a \. And since \ needs to be escaped inside a string literal, you add two:

String[] stringHolder = string.split("_\\(B");
