my compiler errors aren't showing, so it won't show what is wrong with my code! CAN SOMEONE PLEASE FIX THE COMPILER ERROR THING!?!?!??!?!?!?!!?!?!??!?!

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 */
    char lastNameFirstLetter = lastName.charAt(0);
    if (lastNameFirstLetter < 'm') {
      line = 0;
    }
    else {
      line = 1;
    }
    int line = 0;
    return line;
  }

I used the following code for this challenge, I added a few comments. Hope this helps! :)

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 */

    char lastNameFirstLetter = lastName.charAt(0);
    int line = 0; // Declare and Initialize the int variable here before you use it below to make sure it is in scope 

    if (lastNameFirstLetter <= 'M') {   // I added <= so that people with a last name that starts with the letter 'm' would go to line 1
             line = 1; 
    } else {
      line = 2;      // you had "line = 1" here, it should be "line = 2"
    }

    return line;
  }

}

You used the int line before declaring it. Also return line 1 or 2, and check against capital 'M'. Other than that code looks great, great job!

I will try and figure out why this code isn't generating a compiler error on the code challenge engine. Sorry for the frustration!

I already figured out the code challenge, but thanks for the reply anyways!! and also thanks for trying to figure out the bug in the code challenge engine!! I thought that it was line 0 or 1, because you stated in one of this course's videos that 0 comes first. not line 1 or 2.
