C# C# Objects Methods Method Overloading

Initialize and adding parameter c#

The question I have to answer is the following

---Add a second parameter to the constructor named reactionTime after the existing parameter and use it to initialize the value of the ReactionTime field.---

I already asked for help on this question but the answer I was given didn't work and didn't make sense to me. They said I had to create another Boolean method for 'EatFly' but I wasn't sure why. Any help would be great.

Frog.cs 
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;
        public readonly int ReactionTime;
        public Frog(int tongueLength)

        {
            TongueLength = tongueLength;
        }

        public bool EatFly(int distanceToFly)

        {
            return TongueLength >= distanceToFly;
        }

        public bool EatFly(int distanceToFly, int flyReactionTime)
        {
           return TongueLength >= distanceToFly && ReactionTime <= flyReactionTime;
        }

    }

Hi Paul - you need to do some revision on what a constructor class is and then this will make simple sense - the code below is correct for the challenge (I just completed the second part):

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


        //Below is the constructor
        public Frog(int tongueLength, int reactionTime) //The second parameter is placed inside the brackets
        {
            TongueLength = tongueLength;
            ReactionTime = reactionTime; //This is how to initilize the parameter to ReactionTime field
        }

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

Part of the problem is that the wording of the challenge is a bit confusing - it makes it look like the constructor is called reactionTime when infact it is not and that the parameter that needs to be added to the constructor is called reactionTime instead.
