6,333 PointsI'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;
}]
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;
}
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");
}
}

Treehouse TeacherHi 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
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! 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!
