I'm just confused as to why this code isn't working. It says tongueLength doesn't exist...

It's all in the title

Frog.cs
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;
        public readonly int ReactionTime;
        public readonly int FlyReactionTime;
        public readonly int DistanceToFly;

        public Frog(int tongueLength, int reactionTime, int flyReactionTime, int distanceToFly)
        {
            TongueLength = tongueLength;
            ReactionTime = reactionTime;
            FlyReactionTime = flyReactionTime;
            DistanceToFly = distanceToFly;            
        }

        public bool EatFly(int distanceToFly)
        {
            return tongueLength >= distanceToFly;
        }

        public bool EatFly(int distanceToFly, int flyReactionTime)
        {
            return reactionTime <= flyReactionTime;
        }
    }
}

:point_right: The message is incorrect, but I see at least 4 issues that need attention:

  • You added 2 additional parameters to the Frog constructor that are not needed.
  • You changed the name of the variable in the first EatFly method (you should not change this method!)
  • Your new EatFly method (with 2 parameters) is not using the correct variables for comparison.
  • The new method needs to make and combine two comparisons: one for speed, one for length.
