I can't understand this, can you help me?

The question is {"I have modeled an assistant for a tech conference. Since there are so many attendees, registration is broken up into two lines. Lines are determined by last name, and they will end up in line 1 or line 2. Please help me fix the getLineFor method.

NEW INFO: chars can be compared using the > and < symbols. For instance 'B' > 'A' and 'R' < 'Z'"} I couldn't understand what the question meant can anybody help??

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;

  }

}

Basically you need to add an if statement that will check if the first letter in the variable lastName is between A - M if it is set line equal to 1 if the first letter in the variable is greater than 'M' than set line equal to 2, like this:

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;
  }

This question is asking you to write code to determine the line for attendees.

IF the first letter of their last name is a-m (less than n) then their line is 1. If their name is n-z (greater than m) then the line is 2. Once you determine a line then tell them what it is (return it).

public static int getLineFor(String lastName) {
        int line = 0; 
        if (lastName.charAt(0) <= 'M') {
            line = 1; 
        } else {
            line = 2; 
        }
        return line; 
    }
