I think I almost did the challenge though I have this error: Frog.cs(19,16): error CS1520: Class, struct, or interface method must have a return type Compilation failed: 1 error(s), 0 warnings
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 reactionTime(int reactionTime)
{
}
}
}

Courses Plus Student 13,331 PointsI understand that though now I don't know what the return type is

Courses Plus Student 10,205 PointsAh, just checked the challenge, sorry about that.
So the task is asking you to modify the constructor of the class. The reactionTime method should not exist
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
You need to add a reactionTime parameter, and also assign it like they have done for TongueLength.

Courses Plus Student 13,331 Pointsok now it makes more sense . could you just show the code of the same challenge because it tells me that one of my braces are in the wrong place or that there are missing semi colons. I f you show your code it would be easier to me to refer and so I can figure out what I'm doing wrong so I can improve, instead of you telling me directly.
Mathew Tran
Courses Plus Student 10,205 PointsErr, not to be stubborn, but I think it would be good for you to write in the code yourself instead of me giving you the answer.
I've provided comments where you need to update your code to make this challenge pass.
namespace Treehouse.CodeChallenges
{
class Frog
{
public readonly int TongueLength;
// Add public readonly int ReactionTime variable
public Frog(int tongueLength) // Add Parameter, int reactionTime
{
TongueLength = tongueLength;
// Set ReactionTime variable like it is done for tongueLength, but with reactionTime
}
public bool EatFly(int distanceToFly)
{
return TongueLength >= distanceToFly;
}
public readonly int ReactionTime;
public reactionTime(int reactionTime) // Remove this function
{
}
}
}
Hope this helps.

Courses Plus Student 13,331 Pointsdon't worry I'm not copying I have already done the code is just I think my eyesight is a bit off today so nothing to worry I don't like to cheat its only the braces and semicolon. note that I'm part 2 of the stage thanks

Courses Plus Student 10,205 PointsYour
reactionTimefunction might need looking at. The compiler is telling you that the method is expecting a return type.Consider how you worked on the EatFly function.
Note how the return type is bool, and you returned a bool.
Good luck!
