java email extraction regular expression?

Question

I would like a regular expression that will extract email addresses from a String (using Java regular expressions).

That really works.

Answer 1

Here's the regular expression that really works. I've spent an hour surfing on the web and testing different approaches, and most of them didn't work although Google top-ranked those pages.

I want to share with you a working regular expression:

[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})
