I get this syntax error: bad operand types for binary operator ''

Question

bad operand types for binary operator '>'
```ConferenceRegistrationAssistant.java
public class ConferenceRegistrationAssistant {
  public int getLineFor(String lastName) {
    if(lastName > 'M'){
      int line = 1;
    }else {
       int line = 2;
    }return line;
  }
/* If the last name is between A thru M send them to line 1
   Otherwise send them to line 2 */
int line = 0;
}
```

You get the error because you compare String with char. There are different ways to get specific letter from String. You can use methods like chatAt (http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#charAt(int)) or substring. Then you will be able to compare the letters.
Please also think about the case where the first letter of last name is actually equal to 'A' or 'M'.
You should declare int line = 0; only once, then change its value whether person goes to first or second line.
Hope it helps. Good luck!
