could you please someone tell me how to match these types of url in string?

For example:

example.com
www.example.com
http://example.com
https://www.example.com
example.com/exam1/exam.php
example.com/exam
...

Actually, I need to detect all forms of URL you can see for example on Twitter in plain text.

I have tried to find some regex by google but I couldn't find something which fits all the types in Java.

UPDATE: Maybe I wasn't too precise - I need find all these types of url in plain text and replace them by some token. For example: status.replaceAll(yourRegex, "URL");

Thank you!

^(?:https?:\/\/)?(?:www\.)?[a-zA-Z0-9./]+$

Try this.See demo.

Use 

^(?:https?:\/\/)?(?:www\.)?example\.[a-zA-Z0-9./]+$

If you want to match example. something.See demo.

  • It works well but I need detect these urls in plain text (maybe I wasn't too precise in my explanation)) and replace by url token... something like this: status.replaceAll(yourRegex, "_URL_"); – Petr Jirásek Jan 03 '15 at 17:34

This should work reasonably well to match any URL:

(https?://)?\w+(\.\w+)+(/\w+)*(/\w+\.\w+)?(\?[\w%&=.]*)*(?=[^\w.?&%=])

See demo

It matches any number of path parts too, eg `example.com/a/b/c?x=y&a=b
