Validating a email address in java 321chat sex cam
If you are trying to do a form validation received from the client, or just a bean validation - keep it simple.
I'd also stay away from so called simple 'non-restrictive' regex; there's no such thing. Perl5Util which is from a retired Jakarta ORO project.
For example @ is allowed multiple times depending on context, how do you know the required one is there? BTW, I found that there is a 1.4 version, here are the API docs.
It supports only the older RFC-2822 spec though, although appropriate enough for modern needs (RFC-5322 it in areas already out of scope for daily use cases). This means 1.4 has not been made final for three years (2008-2011). I'm looking for a better option, but didn't find one that is very adopted.
But really what you want is a lexer that properly parses a string and breaks it up into the component structure according to the RFC grammar. I want to use something that is well tested, don't want to hit any bugs.
It is not strictly RFC compliant, but works well enough for modern needs.
Today we will look into java email validation program. [email protected] – “.a” is not a valid tld, last tld must contains at least two characters 4. mkyong()*@– email’s is only allow character, digit, underscore and dash 8. [email protected]– email’s first character can not start with dot “.” 7.This question exists because it has historical significance, but it is not considered a good, on-topic question for this site so please do not use it as evidence that you can ask similar questions here.This question and its answers are frozen and cannot be changed.In this real-life example, I am trying to validate email addresses using java regular expression.
