ConferenceRegistrationAssistant

what am i doing wrong here?

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 */
    int line = 0;
    char letter1 = 'a';
    char letter2 = 'm';
    if (letter1 > letter2) {
      line = 2;
    } 
    if (letter1 < letter2) {
      line = 1;
    }
    return line;

Hi Jarren,

in your approach you are comparing the char 'a' with the char 'm'.

a is greater then m and the result of the first if statement is always true + the line 2 is returned because both chars are hardcoded. This is not what this tricky challenge wants you to do :smiley:

For this challenge the examination of the first character of the argument String lastName is needed. If this first char on position 0 of the String is less then M... line 1 should be returned, else line 2 will be returned. You can use the charAt() on the argument to look at the first character inside the String.

You chan use this code:

if(lastName.charAt(0) <= 'M') {
    line = 1;
} else {
    line = 2
}
return line;
}

I hope this helps. Don´t hesitate to ask again if something is not fully clear.

Grigorij
