I'm not sure where to start. Could someone please walk me through this challenge?

I've been working on this for a while, but I am utterly lost. Any help would be greatly appreciated! Thank you!

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;
    return line;
  }

Could also do this extra check so charlie might understand it better seen as though question says between A and M

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 between A and M (the charAt(0) means grab the first letter of my last name)
    if(lastName.charAt(0) >= 'A' && lastName.charAt(0) <= 'M'){
      line = 1;
    }
    else{
      line = 2; 
    }
    return line;
  }

}

Hi Charlie,

  public int getLineFor(String lastName) {
// the line variable is needed to store the line value and return it later on    
int line = 0;

    if (lastName.charAt(0) < 'M') {
// inside the parenthesis get the first character from the argument using the charAt method
// proof it against 'M', so every first char that is less then M will go into line 1

      line = 1;
    } else {
// if the first character of the name is greater then M -> line 2 will be returned
      line = 2;
    }
    return line;
// return the value in dependance of the first character
  }

Makes sense?

I thought we might kind of want to help him with a walk-through step-by-step, instead of just posting the code, but as long as he get's it, this works as well! :-D
