java ip regex
hi i have this regex that finds ip and port ie.121.121.121.121:0000; in a string
"\\d{1,3}(?:\\.\\d{1,3}){3}(?::\\d{1,5})?"
the problem is if the port is missing this regex still finds just the ip which i dont want i want it to be all or nothing ip:port i tought removing the ? at the very end should achieve this but i still have the same problem.
does anyone know how or direct me to the information i need to chainge this to only identifing ip and port.
thanks.

Re: java ip regex
Yes, your problem is the question mark. In a regular expression, the "?" means "Zero or 1 times". In your case of not having the ":0000" on the end would qualify for "Zero times". You were correct to remove the "?" and that should have worked. Could you post a set of code that i could test and see the issue occurring? A workaround may be to put a "{1}". It seems to me like you have an issue that is not just in the regex string.
Writing code is your job, helping you fix and understand it is mine.
