I have a problem with a regex in java.
When I try to use this regex:
^(?:(?:([01]?d|2[0-3]):)?([0-5]?d):)?([0-5]?d)$
I get the following error
"Invalid escape sequence (valid ones are
f
" ' )"
I don't know how to handle that error.
I already tried to double the backslashes, but it didn't work.
I hope someone can help me with this.
Thanks
