Can some one help me with the code

I have model an assistant for a tech conference. Since there are so many attendees, registration is broken up into two lines. Lines are determined by last name, and they will end up in line 1 or line 2. Please help me fix the getLineFor method.

NEW INFO: chars can be compared using the > and < symbols. For instance 'B' > 'A' and 'R' < 'Z'

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 */
    if(lastName.charAt(0)<='m'){
      int line=1;
      return line;
    }else {
      int line = 2;
      return line;
    }
  }

I suspect that your error is due to the last name probably starting with an uppercase letter, but you are testing to see if it has an ASCII value of less than lowercase "m". So, that is not going to work. I suggest that you force the character you are comparing to uppercase then do the comparison (could be done in one line of code). Apologies, but for the moment I cannot think of the code to capitalise the character - but there is a method.
