Regex: Formatting/Multiple Formats

I'm fairly new to Regex, but not new to Java as a coding language. I'm currently trying to create a Regex expression that will format a user's input to two separate values, but I'm a little curious as to how to approach it.

For example, suppose a user were guessing the resulting score of a basketball game, there's a handful of formats they could use: 

     57-89
     57:89
     57/89

etc.

I guess my question is first, how would I go about having my Regex expression handle multiple digits? That is, recognizing a valid guess regardless of how many digits they were to put in for each value. Second of all, how would I go about creating a Regex expression that would handle multiple formats, such as the ones listed above?

Thanks ahead of time.

If the input is in the following format:

<integer><non-integer delimiter><integer>

then this split method will parse it into a String[] with each integer as a separate element:

inputString.split("[^0-9]+");

[^0-9]+ is the regex for the delimiter:

  • [] character class;
  • ^ exclude the following characters;
  • 0-9 character range 0, 1, ..., 9;
  • + one or more occurrences (that means it will work for multicharacter delimiter, e.g. 59 - 87).

More information on Java regexes is here.
