Totally stuck on what to do for getLineFor challenge

Hi,

I am working on chars and using a getLineFor method. I am supposed to send lastNames with the letters A-M to line 1. All other last names go to line 2. Here is the code I have been given to work with. I really don't know where to start on fixing the getLineFor method. Thanks for the help!

ConferenceRegistrationAssistant.java 
public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    /* If the last name is between A thru M send them to line 1
       Otherwise send them to line 2 */
    int line = 0;
    return line;
  }

}

Your are provided the lastName, which is a String. The String class has a metric truckload of member functions which you can use to determine information about or manipulate a String. Try to find a member function in the String class which would determine the first letter in lastName. From there you would know which line to send them to. Something like lastName.memberFunction().

public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    /* If the last name is between A thru M send them to line 1
       Otherwise send them to line 2 */
    int line = 0;
    if(lastName.charAt(0) <= 'M') {
            return line = 1;
     }else {
           return line = 2;
     }
  }
