Write a method, getEmailUserName, that is passed a String argument that is an email address and returns the user-name part.

LANGUAGE: Java

CHALLENGE:

Write a method, getEmailUserName, that is passed a String argument that is an email address and returns the user-name part.
So if “mozart@salzberg.de” is passed, the method returns “mozart”.
Assume that the argument will always be a correctly formatted email address.

SOLUTION:

public static String getEmailUserName(String email){
    String emailUsername = email.substring(0, email.indexOf('@'));
    return emailUsername;
}
