There tip corrects a problem with the previously published tip Email Address Validation Using a Regular Expression. The problem with the original version is that when you enter an email address such as (for example) [email protected], the the function incorrectly returns true. The problem is in the country code. Here’s a corrected version:
public boolean validateEmail(email){ // Input the string for validation // String email = "[email protected]"; // Set the email pattern string Pattern p = Pattern.compile(".+@.+\.[a-z]+"); // Match the given string with the pattern Matcher m = p.matcher(email.getText()); // check whether match is found boolean matchFound = m.matches(); StringTokenizer st = new StringTokenizer(email, "."); String lastToken = null; while (st.hasMoreTokens()) { lastToken = st.nextToken(); } if (matchFound && lastToken.length() >= 2 && email.length() - 1 != lastToken.length()) { // validate the country code return true; } else return false;}
