how do i refer to the first letter of a string?

if i had a last name stevens (for example) how would i refer to the first s to compare it to another character?

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 (lastName
    int line = 0;
    return line;
  }

}

Hi Nicholas,

I think you might be looking for the substring() method. String firstLetter = lastName.substring(0, 1);

Nicholas;

Welcome to Treehouse!

You could use the charAt() method which returns the character located at the String's specified index. The string indexes start from zero. So if you were to have:

String name = "Nicholas";
System.out.println(name.charAt(3));

We would get the letter h printed.

Post back with further questions.

Happy coding,
Ken
