Won't return?

Won't return line 1. Is is supposed to be a string, even though it is originally declared as a variable?

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.charAt(0) >= 'm')  {
      line = ;

    } else {
      line = 2;
    }

    return line;
  }

}

I just put this code in and it worked fine for the challenge. I hope that I didn't run you in too many circles trying to help.

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.charAt(0) < 'N') { line = 1;

} else {
  line = 2;
}

return line;

}

}

Happy Coding:)

You have nothing for it to return in the first part. You have line = ; Try using line = 1;

You didn't add anything to tell the person what line they're going to be in. Try This(modify it to fit the specifications of the challenge needing you to print to the screen):

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.charAt(0) >= 'm') { line = ; System.out.println("You are in line 1."); } else { line = 2; System.out.println("You are in line 2."); }

return line;

}

}

Happy Coding :)

I'm about to go look at the challenge myself so that I can see what exactly it is asking for.

I tried that as well, but unfortunately didn't pass the challenge. :/

haha oh my goodness. I feel so silly now. I see what the issue was. You are comparing it in the opposite direction than you should be. You're asking it in the first if statement if the first letter is greater than or equal to M. Swap the sign around to less than.
