What's the difference between "TongueLength" and "tongueLength" in this code?

I've found a solution after a solid 15 minutes of trying different things but I'm still not 100% sure of the reasoning here

namespace Treehouse.CodeChallenges { class Frog { public readonly int TongueLength;

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

}

if we already established that TongueLength = tongueLength, so why does it matter which one of them I use?

:point_right: One is a passed-in argument, the other is an instance variable.

The constructor arguement tongueLength (little "t") only exists while the class instance is being constructed. But its value is copied into the instance variable TongueLength (big "T"), which persists for the life of the class instance.
