They want me to put people into line one and two. If you can help that would be awesome. If not, I totally understand.

// This is as far as I get. Please tell me all the things I am doing wrong.

public class ConferenceRegistrationAssistant { private char theLines;

public 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; int line = 1; public boolean goToLine(char firstLetterOfLastName) { boolean lineOne = theLines.charOf(firstLetterOfLastName) > 'M'; if (lineOne) { return line; } else { return lineTwo; } } }

ConferenceRegistrationAssistant.java 
public class ConferenceRegistrationAssistant {
  private char theLines;

  public 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;
    int line = 1;
    public boolean goToLine(char firstLetterOfLastName) {
      boolean lineOne = theLines.charOf(firstLetterOfLastName) > 'M';
      if (lineOne) {
      return line;
      } else {
        return lineTwo; 
      }
    }
  }

Thank you for that post. I was wondering if you could quickly explain why there is only 1 variable (line) when we are making to different lines.

Blake Larson yes there are two different lines. But you can think of the "line" variable as holding the number of the line. Line can either be line number one or line number 2. But at the end of the day, it's still a line, right? It's only the number that changes. In fact, we could have 10 lines and still it would only be the number of the line that's changing. We're simply setting up the variable line to hold the number of the line being assigned. Hope that helps!

Yeah it's starting to make sense now. Thank you.
