What is wrong with this code

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'<lastName.char<'M')
    {
    int line = 1 ;
    }
    else 
    {
    int line = 2 ;
    }
    int line = 0;
    return line;
  }

}

Sorry, but you can't write java conditions like algebra: 'A'<lastName.char<'M'

You also can't redeclare a variable multiple times: int line

You need to see what the first character is in each name, and charAt(0) will give you that character, as a char:

  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;
  }
