Regex failure in matching

Question

I have a regex where I try to find this pattern in a text 15:30:55 (it's time). And the Pattern.compile is giving out an error PatternSyntaxException: U_ILLEGAL_ARGUMENT_ERROR

Here is my code

Pattern.compile("[0-9]{1,2}[:][0-9]{1,2}[:][0-9]{1,2}");

I think the pattern should be `[0-9]{2}:[0-9]{2}:[0-9]{2}`, but that aside, it looks valid. Can you post the entire Java code? — Tim Biegeleisen, Feb 09 '18 at 10:51
You should not put `:` into a character class as the first char. `[:]` => `:` and it will work. `[-:]` works, but `[:-]` won't. — Wiktor Stribiżew, Feb 09 '18 at 10:53

Try removing square brackets between colon characters in your regex: [0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}

The regex looks good but it could be more succinct e.g. `\d{1,2}:\d{1,2}:\d{1,2}` – hoipolloi Feb 09 '18 at 11:00
@hoipolloi Yeah this looks better. I just intended to correct the actual problem. Thanks – Alpay Feb 09 '18 at 11:02
Worked pretty good. Using that now – Minasie Shibeshi Feb 09 '18 at 11:05
