Having Trouble with this task, if anyone can help that would be great! Happy Coding!

The Task 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'

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;
    char firstLetter = lastName.charAt(0);
    if (firstLetter > 'N'); {
      line = 1;
    } else { firstLetter < 'N'; 
      line = 2;
           }
  }

}

For starters, you'll want to place the return statement at the end of your function. Also, it looks like the syntax of your conditional statement is incorrect. Conditional statements should look something like the following:

    if (condition1) {
      statement1;
    } else if (condition2) {
      statement2;
    }

Something like:

if (firstLetter < 'N') {
      line = 1;
} else { 
      line = 2;
}

You don't need the second conditional test as they are mutually exclusive - if the first is > 'N' then the second isn't so there's no need to test twice. I also switched the > and < as they were going to the wrong lines.

Then you need to return line after those lines of code else the code will never run.
