2,561 PointsCode is not working, and I don't know why
I feel that my code should work, but for some reason it does not. Can someone please tell me what I'm doing wrong.
namespace Treehouse.CodeChallenges
{
class Frog
{
public readonly int TongueLength;
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
public EatFly(int distanceToFly)
{
bool canEatFly = distanceToFly <= tongueLength;
return canEatFly;
}
}
}

Java Web Development Techdegree Student 2,610 PointsThere are two problems. First, you did not list the return type of bool for your method.
second, you are accessing the wrong tongueLength variable. The one with the lowercase T does not exist in the current context you are using it. It only existed within the scope of the Frog constructor. You need to access the tongue length that is a member of the class (the one with the capital T). Remember, C# is case sensitive, so tongueLength and TongueLength are two different variable names.
here's a handy trick. I have never done the C# track, so I'm not sure you've learned it yet, but the way I would have written this is:
namespace Treehouse.CodeChallenges
{
class Frog
{
public readonly int tongueLength;
public Frog(int tongueLength)
{
this.tongueLength = tongueLength;
}
public bool EatFly(int distanceToFly)
{
bool canEatFly = distanceToFly <= tongueLength;
return canEatFly;
}
}
}
The this keyword points back to the class, so no confusion as to which 'tongue length' is which. The reason I don't have to use thiswhen I reference tongueLength in the eatFly method is because there is no other tongueLength variable to confuse it with, so it is not necessary to state this.
