2,017 PointsI don't understand constructors
I'm completely stalled on constructors. I don't understand how to create or define them and I've watched the video multiple times over the past couple of days. would anybody be able to simplify as basically as they can?

Courses Plus Student 10,205 PointsA Constructor is a function that is called upon creation of an instance of an object. This is where you would usually initialize values.
To create a constructor you need to make a method that returns the class that you are creating. It also needs to be defined within scope of the class.
The scope of the class is the code that is in between the curly braces
class GoKart
{
// This is the class scope where I should define my constructor!
}
This is how to create a constructor, when in class scope.
class GoKart {
public GoKart() // This is a constructor
{
}
}
In the terms of the challenge, it's the same as adding parameters to any other functions. Just add the color attribute of type String as a parameter to the constructor
Hope this helps!
