How Can I Validate Email Addresses in Java Beyond Commons Validator?

Java Email Address Validation: Beyond Commons Validator

When validating email addresses in Java, it's not uncommon to turn to libraries like Commons Validator. However, there are additional robust methods that offer alternative approaches.

Using the Java Email Package

A straightforward solution is leveraging the official Java Email package. This method involves creating an InternetAddress object and invoking its validate() method:

public static boolean isValidEmailAddress(String email) {
   boolean result = true;
   try {
      InternetAddress emailAddr = new InternetAddress(email);
      emailAddr.validate();
   } catch (AddressException ex) {
      result = false;
   }
   return result;
}

This implementation effectively checks for proper email syntax, including valid domain name resolution. Note that this method is not foolproof and may require additional validation if stricter requirements are necessary.
