Validating a email address in java
Think about it this way: I register for your website under the email address . That’s probably going to bounce off of the illustrious mail daemon, but the formatting is fine; it’s a valid email address.To fix this problem, you implement an activation system where, after registering, I am sent an email with a link I must click.This is to verify that I actually own that email address before my account is activated.At this point, why keep parsing email addresses for their format?
Any code can be removed without warning (if it is deemed offensive, damaging or for any other reason).
Regular expressions can also be used to validate that the input conforms to a given format.
