Java Objects, Delivering the MVP Stage 3 Challenge Task 1

I'm having trouble with the code in this. Here is my code:

  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) < 'n') {
     line += 1; 
    } else {
     line += 2;
    }
    return line;
  }

It looks right to me, and I don't get any syntax errors, except when it runs I get "I entered Zimmerman and expected to get back line 2 as Z comes after M".

What am I doing wrong? It looks to me like this should return 2 for a name starting with Z?

Madison,

  • I used N because I assumed if you A - M to go to line 1, that any line where the first letter is less than N is ok. so in Java if I have N < N, would that be true or false?*

N<N would be false, because it is saying "Is N less than N?". Another way to put it would be: lastName <=M

Yours looks good except I assume the last name comes in capitalized, so you should compare with 'N' rather than 'n'.

That was the problem, Thanks!

Quick question about java. I used N because I assumed if you A - M to go to line 1, that any line where the first letter is less than N is ok. so in Java if I have N < N, would that be true or false?
