Error “this method must return a result of type int”?

Question

I have this code below and it keep telling me that thanksgiving() must return a result type of int. I have casted all the results just to make sure, but nothing seems to be work

Answer 1

The problem is that all of your return statements are within an if statement. If, for some reason, day != Thursday, not < thursday, and not > thursday (I know this is impossible), then nothing will be returned. Change your code to have a default return value:

public static int thanksgiving(int year)
{
  int day = firstOfMonth( year );
  if ( day == THURS ) 
  {
    return (int) 22;
  }
  else if ( day > THURS )
  {
    return (int) 29 - ( day - THURS );
  }
  else 
  {
    return (int) 22 + ( THURS + day );
  }
}
