Question

i have a question :

I want to create an app that take a String from user input. This String will be in an email format. So there’s some requirement’s :

1. .(full stop) can’t be placed before @
2. .(full stop) and @ can’t be more than one
3. .(full stop) and @ can’t be side by side

Note : This is NOT a school homework(i just felt that this is like a homework after i typed it), i just want to learn more about String 😀

I already did some research’s but i still can’t solve those problem’s 😀

Thanks all, and sory if i made some mistake’s, English is not my native languange 😀

Answer 1

This is Universal Email Validation For Email

 if(eMailValidation(YourEmailString)){
          /// right  Email-id
      }
    public boolean eMailValidation(String emailstring) {
            Pattern emailPattern = Pattern.compile(".+@.+\\.[a-z]+");
            Matcher emailMatcher = emailPattern.matcher(emailstring);
            return emailMatcher.matches();
        }
