How to Add a public constructor to the GoKart.java class that allows the parameter color to be passed in. In the constructor store the argument color in the private color field.

GoKart.java 
public class GoKart {
  private String mColor = "red";

    return mColor;
  }
}

Hiya,

The constructor is always called the same as the class - it is what runs when an instance of the class is created.

In this case, we want to be able to create the instance of the class and have a GoKart of a selected colour result.

So, the constructor is called like: GoKart greenCart = new GoKart("green"); so we need to add a method to do that.

Something like:

public GoKart(String color) {
    mColor = color;
}

So, the class is created and the member variable, mColor is set to the string passed into the constructor as a parameter.

I hope that makes sense!

Steve.
