Java Java Objects (Retired) Creating the MVP Comparing Characters

Comparing Characters challenge error, any thoughts/advice?

I have modeled an assistant for a tech conference. Since there are so many attendees, registration is broken up into two lines. Lines are determined by last name, and they will end up in line 1 or line 2. Please help me fix the getLineFor method.

NEW INFO: chars can be compared using the > and < symbols. For instance 'B' > 'A' and 'R' < 'Z' Bummer! I entered Anderson and expected to get back line 1 as A comes before M.

Not sure why my code isn't solving the above problem. Any advice?

Sorry this is my first time asking a question and i'm just wondering why I can't see my code when I checkmarked the box that said "attach my code"?

Hi Swagat,

The "attach my code" button is a little bit buggy right now. You can post your code with the correct formatting using this guide. However, passing code would be as follows;

public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    int line = 0;
    if(lastName.charAt(0) > 'M') {
      return line = 2;
    } else
    return line = 1;
  }
}

Please let me know if you have any questions about why this works!

Hey Swagat,

look at my suggested code:

public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    int line = 0;
    if(lastName.charAt(0) > 'M') {
// the getLineFor method takes a String "lastName" as argument
// Strings are concatenations of characters and they can be count from 0 
// you can use the charAt() method to compare the char at the place 0 inside String "lastName"
// with a single character of your interest
// here we write a condition:  if char at position 0 of the  "lastName" is greater then character 'M'
// the line is 2

      return line = 2;
// return int 2
    } else
// everething is under 'M'
// line  is 1
    return line = 1;
// return int 1
  }
}

I hope I could help a little and don´t hesitate to ask more questions if you need :)
