Hey samuel,

try this code! I commended it a little:

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
  }
}

Does it make sense?

Grigorij

charAt(int index) returns the character located at the String's specified index. The string indexes start from zero. eg:

    /* 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'){
      // if last name is less than "m"
    }else{
   // if is greater
    }
