Regex to matches a url with or without http in java

I want to validate a url that is with or without http. i tried ^http(s{0,1})://[a-zA-Z0-9_/\-\.]+\.([A-Za-z/]{2,5})[a-zA-Z0-9_/\&\?\=\-\.\~\%]*

But this is matches http://google.com but not www.google.com. i want a regex that matches www.google.com too.

Thanks

Try starting your regex with ^(https?://)? instead of ^http(s{0,1})://
