Java Java Objects (Retired) Creating the MVP Comparing Characters

Can't able to solve the challenge

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;

if(lastName.contains("A") && lastName.contains("M"))
{
  line=line+1;
    return line;
  }
else{
  line=line+2;
  return line;
}
} }

Hi there. Here's one way the editor will accept:

  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') {
        line = 1;
    } else {
        line = 2;
    }
    return line;
  }

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;
    String ABC = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    if(ABC.indexOf(lastName.charAt(0)) <= 12){
      line = 1;
    }else{
      line = 2;   
    }
    return line; 
  }
}
