Code for validating email in java

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.

You can provide custom validation for your forms in two ways: server-side validation and client-side validation.

Server-side validation incorporates code validation into a form handler. NET application on the server that provides the functionality that your form needs for processing after a customer has submitted it.

Because the code is stored on the server, server-side validation requires a roundtrip to the server.

If this type of address is undesired (and it usually is), then some extra validation will be needed.

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.

Validating email is a very important point while validating an HTML form. You can modify or rewrite the said regular expression.
