Aditya,

The "init" or initializer method is something you will see in every programming language. The purpose of the init method varies between and languages and on the intention of the programmer, but here's the general definition of an initializer method.

So, lets say you want to make a new instance of a class called "car." I know this is basic, but it is not easy to understand hard subjects without understanding the underlying components. Pretend we have already created the Car class, and now we want to spawn one in our game. We will call: car1 = Car.init("Ferrari", 200, "red"). In this initializer, the method is taking a car name, a top speed, and a color. Using this information, the Car class will make the room for storage, and return a new instance of the car already stored in memory. Now we can use the car.

I hope you found this useful. If you have any questions, feel free to ask!
