I don't know how to code that in Java Objects Chapter Exercise

Hello

I am begginer in Java and I do not know how to code this exercise. Maybe it is because I do not understand clearly what it is about. I know English very well but sometimes I don't get what is idea of someone who is giving this exercise and what to do.

If someone could help me with it it would be great.

Thanks in advance :-).

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

  }

So you're returning an int but in your code you're trying to add a string(char) to line1 or line2?

line1 += lastName.charAt(0);
line2 += lastName.charAt(0);

From what i'm seeing is that you're suppose to just add 1 person to the end of the line and return the line so 

line1++
line2++

might work?

It should look 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;
  }
