I don't understand the question, do I ?

/* If the last name is between A thru M send them to line 1
       Otherwise send them to line 2 */

You need to write an if statement so if the first letter of the lastname is a through m you would set the line variable to 1 otherwise 2

public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {

    int line = 0;
    return line;

    if ( lastName.charAt(0) >= 'A' && lastName.charAt(0) =< 'M' ) {
      line = 1;
    } else {
      line = 2;
    }

    return line;
  }

}

That's what I did...

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;

    char a = lastName.charAt(0);

    if ( a >= 'A' && a < 'M' ) {
      line = 1;
    } else if ( a > 'M' && a >= 'Z') {
      line = 2;
    }

    return line;

  }

}

Does not work... what am I doing wrong ?

You have 2 return line; lines. You need to remove the first one directly after you set the line variable to 0.

    int line = 0;
    return line;

    char a = lastName.charAt(0);

    if ( a >= 'A' && a < 'M' ) {
      line = 1;
    } else if ( a > 'M' && a >= 'Z') {
      line = 2;
    }

    return line;

becomes

    int line = 0;

    char a = lastName.charAt(0);

    if ( a >= 'A' && a < 'M' ) {
      line = 1;
    } else if ( a > 'M' && a >= 'Z') {
      line = 2;
    }

    return line;
