How to test 3 adress with comma seperator in regex code at the end ";" ,

Bellow the example of  code java

public static void main(String[] args) {

        String emailList = "[email protected]; [email protected]; [email protected];";

        String regex = "^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}(\\s*;\\s*[a-zA-Z0-       9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}){2}$";

        Pattern pattern = Pattern.compile(regex);

        Matcher matcher = pattern.matcher(emailList);

        if (matcher.matches()) {

            System.out.println("Valid email addresses format.");

        } else {

            System.out.println("Invalid email addresses format.");

        }
