Need help with the getLineFor method in stage 3 Creating the MVP exercise

I am having a problem coding the method so it will return a value of line1 or line2

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

}

Just curious on why did you use line = 0 as the condition instead of 'A' > 'M' ??

Line = 0 is only used for initialization. we are only to use line 1 and 2.

int line = 0;
    if ( line = 0 ) {
      'A' < 'M';
    } else {
     line = 2;

you initialized line as ...int line =0; now when you say if (line =0) what are you saying cause you have already set line as equal to zero above. also there is no need to say 'A' < 'M'. what we need to do is to check if the first letter of the last name is less than N (between A thru M) to put it in line 1. Try the code below and notify me if it helps

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;
    char letter = lastName.indexOf(0);
    if(letter < 'N'){
      line = 1;
    } else {
     line = 2; 
    }
    return line;
  }

}
