Regexp to match domain and subdomains (in Java)

Question

I need to verify if given URL matches my domain mask.

Example: I want to allow only domains which satisfy this \"pseudo-mask\":

https://*.domain.com
         


        

Answer 1

you can use

"http://a.domain.com".indexOf("domain.com") 

this will return -1 if the requested string is not in the text.

since you can don't want '.' after 'domain.com'

you can can use

"http://a.domain.com".indexOf("domain.com.")

and check whether it is -1 or not
