Java code for validating email address

The following example shows how you can validate an email address for a form.This javascript validation code is cross browser compatible (works for all browsers).Here’s a Java example to show you how to use regex to validate email address. [email protected], [email protected], [email protected] [email protected], [email protected], [email protected] 3. [email protected]%*– email’s tld is only allow character and digit 9. [email protected]– email’s last character can not end with dot “.” 11. [email protected] -email’s tld which has two characters can not contains digit Here’s a unit test using test NG.Our email validation API uses a multi-layer testing algorithm that runs multiple checks to find out if an email address is really valid and accepts mail. Our Email Validator uses a multi-layer checking process, with every single email going through all of these validation and verification steps: During the entire process, we never send any email to the recipient address. Here's what I have so far not sure how to write it Weird Ok I figured out it wont take val--dation.So now everything is Val or Val Error --------------------------------------------------------------------------- if (Phone Number.equals("")) if (Email Address.equals("")) if (val == true) else ---------------------------------------------------------------------------- [ December 14, 2004: Message edited by: Jim Shapt ] tough going.

In forms when using email ID fields it is a good idea to use client side validation along with your programming language validation.To get you going (and to save you having to read RFC822) I'll can extend on what Jeroen has already told you: SMTP email addresses do not need to include an '@' sign. And can be "unfolded" - which means they span more then one line. If this is all you want to check for, then you can just use some methods in the String class.In particular, index Of() and last Index Of() might be particularly useful.Feel free to post here as you are thinking about the issues involved. Layne Well any time I've tackled this I've always used regualr expressions: (\w.) @\w (.[\w]) will get you started for the email but you'll have to look up the specifications to gather all valid characters in an address As with phone numbers if you'll only accept digits you're it's straight forward (\d) but you might want to give some leeway and say between 6 & 10 digits (\d) Hope this helps, Barry I'd recommend using the internet.Hopefully the questions above sparked some thoughts. Interet Address class to validate SMTP email addresses since it will do it all for you (there nothing out the box if you want to validate another protocol).
