Getters and setters, can't figure out the value I must set.

As far as I understand, I have to get and set the value to _numFliesEaten. I think that I got the value, but I have no clue how to set it!

It feels strange since in the video before challenge there was MapLocation field to which value could be assigned, but here there is no field to which I can assign any value.

Frog.cs 
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        private int _numFliesEaten;

        public int GetNumFliesEaten()
        {
          return _numFliesEaten;
        }

        public void SetNumFliesEaten()
        {
          _numFliesEaten = ??;
        }



    }
}

Remember you will be setting the _numflieseaten variable from another class using the constructor. You cannot change the private variable so you must equal it to the value passed into the parameter.

namespace Treehouse.CodeChallenges { class Frog { private int _numFliesEaten;

    public int GetNumFliesEaten()
    {
      return _numFliesEaten;
    }

    public void SetNumFliesEaten(int x)
    {
      _numFliesEaten = x;
    }



}

}

Why is 'int' required for the getter but not the setter?

Mohammad Hanbali int is the return type. A set will not return. So it will be a void.

Yes that was what I was doing wrong! Thanks
