Invalid regular expression nothing to repeat exception for email validation using regular expression

Question

Getting the exception when validating the email using regular expression

Using the below line of code

.match("^[A-Z0-9._%+-]++@[A-Z0-9.-]++.[A-Z]{2,}+$")

It seems you didnt escape some characters like the double + Try using an online editor as most descripe issues in the syntax pretty good (https://regexr.com/) — TSH, Feb 11 '20 at 07:30

It's the extra "+"s. Have you tried

.match("^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,}$")

P.S. you are only matching full-capital addresses without "a-z".
