Taking all these into account some valid email addresses are: Email ID [email protected] is valid?

false Email ID journaldev()[email protected] is valid? false Email ID journaldev..[email protected] is valid?

There may be more usecase but that’s not point of discussion here. validating email address in java using regular expressions.

List emails = new Array List(); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("[email protected]"); emails.add("user#@in"); emails.add("[email protected]"); //Invalid emails emails.add("user#domain.com"); emails.add("@yahoo.com"); String regex = "^(. )$"; Pattern pattern = Pattern.compile(regex); for(String email : emails) Output: [email protected]: true [email protected] : true [email protected]: true [email protected]: true user#@in : true [email protected] : true user#: false @: false In this regex, we have added some restriction osn username part of email address.

This uses the Internet Address class which has most of the RFC mail address checks implmented.
