C# C# Objects Methods Method Overloading

got confused

Can anyone help me! I started C#, then had to stop it for a few weeks and now I am stuck on this challenge and I don't know the answer to the question and I forgot what is a parameter and what is a constructor. Also where is the video that deals with it, as I can't listen to all of the videos again. A big thank you.

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

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }

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

        public readonly int ReactionTime;

        public int reactionTime(ReactionTime)
        {
            reactionTime = ReactionTime;

            return int reactionTime(ReactionTime);
        }
    }
}

Hey! A parameter is something that defines what arguments you can pass into a method when calling it, so in C# that's the bits in parenthesis, for example int distanceToFly in this line:

public bool EatFly(int distanceToFly)

A constructor in C# is a special type of method that is used to make a new instance (a new object) of a given class. Like other methods, it can also take parameters. You can always identify the constructor by looking for the thing that has the same name as the class (unlike normal methods, it will also have no void or return type stated as this isn't applicable to a constructor).

So in this example, the constructor is:

public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }

And therefore the solution would be:

public Frog(int tongueLength, int reactionTime)
        {
            TongueLength = tongueLength;
            ReactionTime = reactionTime;
        }

If it is still confusing, it might make sense to re-watch the videos as this is quite important stuff to get your head around it, you'll use it all the time in C#!
