Java Java Objects Creating the MVP Conference Registration Assistant

I've created a tool to help manage lines at tech conferences. The organizers would like to split the attendees into two

ublic int getLineNumberFor(String lastName) { int lineNumber = 0;

char lastNameFirstChar = lastName.charAt(0);
if (lastNameFirstChar >= 'A' && lastNameFirstChar <= 'M') {
  lineNumber = 1;
} else {
  lineNumber = 2;
}
return lineNumber;

}]

ConferenceRegistrationAssistant.java
public int getLineNumberFor(String lastName) {
    int lineNumber = 0;

    char lastNameFirstChar = lastName.charAt(0);
    if (lastNameFirstChar >= 'A' && lastNameFirstChar <= 'M') {
      lineNumber = 1;
    } else {
      lineNumber = 2;
    }
    return lineNumber;
  }
Example.java
public class Example {

  public static void main(String[] args) {
    /*
      IMPORTANT:  You can compare characters using <, >. <=, >= and == just like numbers
     */
    if ('C' < 'D') {
      System.out.println("C comes before D");
    }

    if ('B' > 'A') {
      System.out.println("B comes after A");
    }

    if ('E' >= 'E') {
      System.out.println("E is equal to or comes after E");
    }

    // This code is here for demonstration purposes only...
    ConferenceRegistrationAssistant assistant = new ConferenceRegistrationAssistant();
    /*
      Remember that there are 2 lines.
      Line #1 is for A-M
      Line #2 is for N-Z
     */
    int lineNumber = 0;
    /*
      This should set lineNumber to 2 because
      The last name is Zimmerman which starts with a Z.
      Therefore it is between N-Z
     */
    lineNumber = assistant.getLineNumberFor("Zimmerman");

    /*
      This method call should set lineNumber to 1, because 'A' from "Anderson" is between A-M.
     */
    lineNumber = assistant.getLineNumberFor("Anderson");

    /*
      Likewise Charlie Brown's 'B' is between 'A' and 'M', so lineNumber should be set to 1
     */
    lineNumber = assistant.getLineNumberFor("Brown");
  }

}

Hi Prince Chinyadza ! I received a request for an answer on this question. However, I don't see a question. That being said, I did try your code in the challenge and it passed for me. Plus, the logic looks solid :smiley:

If it's not passing for you, I would suggest copying the code you have in the ConferenceRegistrationAssistant.java file and restarting the challenge and pasting it in again and trying. Because the code there is fine! :tada: It could be something cached either client side or server side. You might try logging out and back in again, but that code is spot on!

Hope this helps! :sparkles:
