i think this is in the wrong group, but String.indexOf is your answer

There is an implemetation provided in struts validator frame work to check whether it is email or not. There is an "isEmail()" method available in org.apache.commons.validator.GenericValidator class which is available in commons-validator.jar, can be downloadable from struts.apache.org

Assuming we are talking about addresses for SMTP, valid SMTP email addresses can have spaces in them.

Also the class InternetAddress packaged with JavaMail will validate an address as part of its constructor, unless you tell it otherwise. So if you are eventually using the address to send mail, then this is a perhaps a more sensible route than including extra 3rd party dependancies.
