Simple Email Validation in java

hi
I was in need of ur help for my project.
I was building a Eshopping store using Core java components.
I want to validate the EMAIL ADDRESS using @ and . signs.
So can anyone help me regarding this.
This is not a web application, only a stand alone application.

Email validation is best done the same way across most platforms - using Regular Expressions. There are quite a few resources available on Google for this very topic.

Syntax Check-Validates the address for syntax, whether it has all of the mandatory characters present (e.g. @) and any illegal characters present (i.e. ~). It will also check for multiple occurrences of required characters (i.e. @@).

DNS/MX Record Check-Validates the domain name with DNS server to ensure that the email domain is a valid registered domain.

Mail Server Check-Validates an email address (e.g. jvsoft@hotpop.com) by mail server (e.g. mail.hotpop.com) to ensure that the mail server indeed has the email address. This method has very good performance. (Attention: a few mail servers don't support this method(e.g. yahoo))
