# Help with ConferenceRegistrationAssistance

Hi! I have a really hard time understanding what to do in this exercise. Something like if(lastName[0].indexOf(a-m)) return 1; else return 2;

terrible coding, I know, but I'm at a loss...

ConferenceRegistrationAssistant.java
```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;
if(lastName[0].indexOf('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm'))
return 1;
else
return 2;
/*
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;
}

}
```
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");
}

}
```

Oh, forgot to write the challange: Fix the getLineNumberFor method to return a 1 if the first character of lastName is between A and M or else return 2 if it is between N and Z.

String Sequence = "abcdefghilklm"; if(Sequence.contains(lastName.CharAt(0)+"") return 1; else return 2;

......

Hmm, doesn't seem to work. Can't find symbol...

I guess you missed a spelling or something of the kind, I tried the challenge and it worked.

try this

```String sequence = "ABCDEFGHIJKLM";
if(sequence.contains((lastName.charAt(0)+"").toUpperCase()))
{
lineNumber = 1;
}else
{
lineNumber = 2;
}
```

That should do it!

Alright man, thanks a lot, it worked! Think I missed setting the lineNumber at the end.

Challange seems a bit too hard at this early point. Don't even remember having learned this type of code before...

Anyway thanks again for your time and help :)
