How do you check if a URL is valid or not in Java?

We can use java. net. url class to validate a URL. The idea is to create a URL object from the specified String representation.

What is a good regex to match a URL?

@:%_\+~#= , to match the domain/sub domain name.

How do I check if a URL is valid?

You can use the URLConstructor to check if a string is a valid URL. URLConstructor ( new URL(url) ) returns a newly created URL object defined by the URL parameters. A JavaScript TypeError exception is thrown if the given URL is not valid.

This works:

Pattern p = Pattern.compile("(@)?(href=')?(HREF=')?(HREF=\")?(href=\")?(http://)?[a-zA-Z_0-9\\-]+(\\.\\w[a-zA-Z_0-9\\-]+)+(/[#&\\n\\-=?\\+\\%/\\.\\w]+)?");  

    Matcher m = p.matcher("your url here");
