match one or more in regex
I have a regex like this:
[ABC]ddd
which matches strings like B434 or A919 but does not match strings like B434-3 or B232-8
I've tried modifying the regex to: [ABC]ddd(-d)*, however, for what I'm doing I need to do this without a match group. Is this possible to do?
Question
Is it possible to have a regex that matches (for example) B434 as well as B341-3 without match groups?

If you want to match the dash digit part only once, you could use an optional non capturing group[ABC]ddd(?:-d)?

Here is what you need:
[ABC]ddd(?:-d)?
the ?: will make it a Non-capturing group.

We could also use the pattern below:
import scala.util.matching.Regex
val setPattern: Regex = """[A-Z-0-9]""".r
