Return type integer

public class ConferenceRegistrationAssistant { public int line1; public int line2;

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.charAt(0) <= 'M') { System.out.println("This guy belongs to line 1"); return line1; } else { System.out.println("This guy belong tos line 2"); return line2; } } }

The question asked to return line 1 or 2 which both are integers. When I run this code it says that it fails for the name anderson. Can you point out my error and suggest a solution.

ConferenceRegistrationAssistant.java 
public class ConferenceRegistrationAssistant {
  public int line1;
  public int line2;

  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.charAt(0) <= 'M') {
      System.out.println("This guy belongs to line 1");
      return line1;
      } else {
      System.out.println("This guy belong tos line 2");
      return line2;
      }
  }
}

Hi Wajhiulla,

I did a long answer to this challenge a while ago but can't find it now - try and search, by all means.

However, I think I can see where you're getting frustrated.

Have a try with the following code and let me know if that doesn't make sense to you.

Steve. 

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

Your code is mostly correct, but the way you handled the line variable is what's giving you trouble.

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(lastName.charAt(0) <= 'M') {
           System.out.println("This guy belongs to line 1");
           return line = 1;
      } else {
           System.out.println("This guy belong tos line 2");
           return line = 2;
      }
  }
}
