Code Challenge "Comparing Characters"

Challenge Task 1 of 1

I have modeled 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 */
    int line = 0;
    return line;
  }

}

Hi Isaiah-

What they're asking for is this logic: If the first letter of lastName comes before (is less than) N, set the line to 1. Otherwise set the line to two.

In Code:

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 */

//create a line variable
  int line = 0;

//if the first letter of the last name comes before N...
    if (lastName.charAt(0)<'N') {

      //set the line to 1
      line=1;
    } 

//otherwise...
else {

      //set the line to 2
      line=2;
    }

    //return the line the person belongs in
    return line;
  }

}
