5,665 PointsHelp with constructor class? ( I don't actually know what it is.... -_-)
Would appreciate if someone can explain why we can use a class/constructor as an array..does it mean it only contains what the getter gives us, which in this case the TongueLength? But when we declare Frog in other classes it needs to take a parameter.. so we are actually setting it...? but it doesn't have a setter..? i am truly a mess errgh. Thank you in advance :P
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
int tongueLength;
for(int i = 0; i < frogs.Length; i++)
{
tongueLength += frogs[i].TongueLength;
}
return (double) tongueLength / frogs.Length ;
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}

5,885 PointsIn GetAverageTongueLength, you are not actually using the constructor or the class as an array. GetAverageTongueLength is a method that expects you to input an array of Frog objects.
First, you need to create those frog objects, like this:
And yes, you need to set the tongue length when creating the Frog object. Frog constructor takes the length as a parameter and sets it in the code to TongueLength. Then you would create a new array of the class Frog, put those Frog objects into that array. You can then finally use this array to call the FrogStats' method.
