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

Thanks to @Jason Buberel's answer, I think lowercase letters must be validated by the RegEX. So the following is correct:

[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,6}

Now, both developer961@mail.com and DEV961@yahoo.COM are valid!
Note that \. should be \\. to escape . and have \. itself. Since, . is a meaningful character in java RegEX means all characters.
