How am I supposed to send someone to line 1 or line 2?

I undesrtand the condition and everything but how am I supposed to send someone to line 1 or 2. Do I need to declare other variables for those or what?

ConferenceRegistrationAssistant.java 
public class ConferenceRegistrationAssistant {
     public String line1;
    public String line2;
  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 */

    if (lastName.charAt(0) >'M') {
      line2 = lastName;
      return line2;
    } else {
      line1 = lastName;
      return line1;
    }


}

Hey Emanuel,

I think you might be overthinking the code challenge.

You don't need to declare line1 and line2 as class fields because you're not creating a class constructor, getLineFor() is a method.

Once you delete the class fields, line1 and line2, you can simplify your method to:

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

}

Does that help you? Let me know if you have any more questions.

Oh, yes. I can see now. I was a little bit confused with the line variable and with the instruction of sending someone there. I thought I needed to declare other variables for line 1 and line 2. Thanks a lot, I simplified it and it now works.
