Not getting the answer of this code

I have compared the letters by charAt method but still not getting the answer.

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 line1 = 0;
    int line2 = 0;
    char letter = lastName.charAt(0);
    if(letter <= 'M') {
      return ++line1;
    } else {
      if(letter > 'M') {
      return ++line2;
    }
   }
}

They require return line = 1 or line=2, and that you use if else, I realize this when I run two if instead an if else and they indicate so. 

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;
    char letter = lastName.charAt(0);
    if(letter < 'M') {
      line =1 ;
    } 
    else{
      line=2;
   }
   return line;
 }
}

Hope this helps.

should probably be < 'N' . However, i don't think they do boundary tests on this challenge, so you can get away with it.
