Java regex email

Question

First of all, I know that using regex for email is not recommended but I gotta test this out.

I have this regex:

\\b[A-Z0-9._%-]+@[A-Z0-9.-]+\\.[A-Z]         


        

Answer 1

That's because you are forgetting case insensitivity :

Pattern regex = Pattern.compile("\\b[\\w.%-]+@[-.\\w]+\\.[A-Za-z]{2,4}\\b");

This matches your example, although it ignores many valid e-mails.
