Regular expression for validating email in java
It’s surprisingly easy, and you’re probably already doing it anyway. If you’re going to send an activation email to users, why bother using a gigantic regular expression?
They can get ridiculously convoluted as in the case above and, according to the specification, are often too strict anyway.
If you actually check the Google query I linked above, people have been writing (or trying to write) RFC-compliant regular expressions to parse email addresses for years.
Then I created a variable that contains the result of running the test() function on the phone Number string which will be a boolean that contain either true if the string matches our regular expression or false if it does not.
Now let’s jump into the fun part which is discussing the regular expression First we have the starting and ending slashes “/” , the expression then starts with a “^” sign to match with the beginning of the string.
