Java Java Objects (Retired) Creating the MVP Comparing Characters

where is the mistake

line 8

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 */
      if ('A' < lastNmae.chars < 'M' )
    {
      int line = 1 ;
    }
    else 
    {
    int line = 2;
    }
    int line = 0;
    return line;
    int line = 0;
    return line;
  }

}

You do not need to keep declaring the variable every time you write it. If you use a local variable inside a method just declare and initialize it once like: int line = 0; Then afterwards within the same method you can just write: line = 2; for example.

You don't have to use ".chars" as a property, the "hint" is telling you that characters can be compared with those operators. You can use the method "str.charAt(0)" to see if the strings starts with a given letter:

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

    return line;
  }

}

I hope that helps a little bit.

yp , it does thank you

It looks like your variable lastName is spelled incorrectly.
