a "personal_info" and a domain, that is [email protected] The length of the personal_info part may be up to 64 characters long and domain name may be up to 253 characters. The personal_info part contains the following ASCII characters.

To get a valid email id we use a regular expression /^\w ([\.-]?

The email’s domain name must start with “A-Za-z0-9-“, follow by first level Tld (.com, .net) “.[A-Za-z0-9]” and optional follow by a second level Tld (au, my) “\\.[A-Za-z]”, where second level Tld must start with a dot “.” and length must equal or more than 2 characters.

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.

Though, depending on the use case (web form), you might want to treat them as invalid. Here we go: After actually trying to build my project, it seems apache commons doesn't work with Android very well, hundreds of warnings and some errors, it didn't even compile.

I suspect that Internet Address constructor has been tampered with. This is what I ended up using howtodoinjava.com/2014/11/11/java-regex-validate-email-addre‌​ss If you are trying to do a form validation received from the client, or just a bean validation - keep it simple. (For more information on how to create form validation using the Front Page form feature, see About creating forms in Front Page 2003.) However, if the form validation provided in Front Page does not suit your needs or the site on which you are working is hosted on a server that does not have Front Page Server Extensions from Microsoft installed, you may need to create custom form validation.Note Front Page Server Extensions are a set of programs that provide access to special Front Page features, such as database processing, form processing, hit counters, and other built-in Front Page components that require server-side processing.Restrictions in above regex are:1) A-Z characters allowed 2) a-z characters allowed 3) 0-9 numbers allowed 4) Additionally email may contain only dot(.), dash(-) and underscore(_) 5) Rest all characters are not allowed Let’s test some email addresses against above regex.List emails = new Array List(); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); //Invalid emails emails.add("@yahoo.com"); String regex = "^[A-Za-z0-9 _.-] @(.This article assumes a general understanding of HTML and Java Script.
