What is wrong with this code?

ConferenceRegistrationAssistant.java 
public class ConferenceRegistrationAssistant {

  public int line;

  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 */
    if (lastName.charAt(0) <= 'M') {
    line = 1;
    }
    if (lastName.charAt(0) >= 'N') {
    line = 2;
    }
    int line = 0;
    return line;
  }

}

Try this modification:

public class ConferenceRegistrationAssistant {

  public int line;

  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) <= 'M') {
        line = 1;
    }else{
        line = 2;
    }
    return line;
  }

}

Notice that initialization of variable line occurs before if statements. In your solution, first issue is that line is not declared before assigning value to it, second is that before return statement you always override value with 0. I also changed your if statement.
