2,520 PointsVery Confused!
I am very confused on how to write this code. I simply do not understand it. If someone could help me write this out and explain why we need the different parts that would be awesome, thanks!
public class Example {
public static void main(String[] args) {
System.out.println("We are going to create a GoKart");
public}
}

public static void main(String[] args) {
System.out.println("We are going to create a GoKart");
GoKart goKart = new GoKart("Red"); // this line instantiates an object from class GoKart; I gave it the name goKart (it could have been named anything).
System.out.printf("The color of our new gokart is %s.", goKart.getColor()); //using the new object we created (goKart) I called its method getColor(),
//which should return the color that we passed in when we instantiated the object (red).
//in order to see what is going on you need to understand how the class GoKart was written,
//because you are instantiating an object from it so you can use its methods.

29,567 PointsIf you are wondering how the program knows to accept a color when you instantiate the object it is because when you created the class GoKart you created what is called a "constructor" that takes one String parameter (in this case) for your color so any time that you instantiate an object from class GoKart it will always expect a string to be passed in as an argument when you instantiate the object. So in class GoKart your constructor would have looked like this:
