how to validate an email with pattern object

[valery]

I'm trying to validate an email with pattern object.
and it validates only 'xxxxx@'
I want that validates all 'xxx@zzz.yy'
the code is the following one:

Code:

  
public static boolean validateEmail(String ca) {
        Pattern pattern= Pattern.compile("[a-zA-Z0-9_]+[.[a-zA-Z0-9]+]*@[a-zA-Z0-9_]+[.[a-zA-Z]+]+");
        Matcher en= pattern.matcher(ca);
        return !en.matches();
    }

what's the problem?
what am I doing wrong?

From a quick glance I would say you have forgotton to escape the '.' character. In regex the . defines any character so to explicitly search for just a . you need \. instead.
Also remember as this is in a string the \ character is a java string escape character so you actually need to escape that as well.

So basically replace . with \\. and that will get you going again.

Whenever I am doing regex I always keep a cheat sheet to hand which I found on Web design, development and marketing - ILoveJackDaniels.com

Hope this helps.
