I am not sure how to set this up. I thought I could look for a character and then create an if else statement that requires the char that was input to exists in one of two categories: Line 1 or Line 2. However, when I tried to write the if else statement the workspace did not like that. Cna anyone help?
import java.util.Scanner;
public class ConferenceRegistrationAssistant {
/**
* Assists in guiding people to the proper line based on their last name.
*
* @param lastName The person's last name
* @return The line number based on the first letter of lastName
*/
public int getLineNumberFor(String lastName) {
int lineNumber = 0;
Scanner scanner = new Scanner(System.in);
System.out.print("Enter a lastname: ");
Integer lastName = scanner.nextLine();
char lastName = lastName.charAt(0);
return example.applyLineNumber(lastname);
/*
lineNumber should be set based on the first character of the person's last name
Line 1 - A thru M
Line 2 - N thru Z
*/
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");
}
}

You need to pick up the first character of the lastName
using charAt(0)
then decide if it is 'greater' or 'lesser' than 'M'. If the former, make line
equal to 1, else line
equals 2. Return line
out of the method.
Have a look at this post I wrote a while ago that goes into more detail.
Let me know how you get on.
Steve.
