通过NOT开头的String匹配正则表达式？

Question

I have a string of a score between two people. The database I'm pulling these scores from puts a dash between the scores... So normally the score would look something like:

2-3

I am trying to split these two scores into a String[] in Java.

match.get("scores").toString().split("-", 1)

The problem is, what happens if the scores are negative:

-2--3

What I would need to do now is split by the first dash it finds that ISN'T the first character in the string.

How would I change my .split(RegEx, 1) so that I can match the dash as not the first character?

Answer 1

You can split using this:

.split("(?<=\\d)-");

(?<=) is a positive look-behind. Just google positive-lookbehind regex and you should find plenty of information about it.
