Question about the getLineNumberFor exercise.

My code keeps receiving the error: "Hmmm, I entered "Nelson" for the lastName and expected line number 2 to be returned, but instead it was 1" Or when tweaked it give an error with the last name "Mandela" being placed in line 2. I have been at this for longer than I feel comfortable admitting. Any help would be greatly appreciated.

public class ConferenceRegistrationAssistant {


  public int getLineNumberFor(String lastName) {
    int lineNumber = 0; 
    if (lastName.charAt(0) <=  'm') 
      lineNumber = 1;
    else 
      lineNumber = 2;

    return lineNumber;
  }

}

Glad to see you came up and figured the logic, the only correction is using m instead of using the Uppercase M.

Please see my code below and let me if it works.

public int getLineNumberFor(String lastName) {
    int lineNumber = 0;

    char letter = lastName.charAt(0);
     if (letter <= 'M') {

     lineNumber = 1;
     }

    else{
    lineNumber = 2;
    }
    return lineNumber;
  }

Happy coding
