The dependency injection Dagger basics and the concepts are demonstrated in different branches

class Engine

class Wheels

class Car constructor(engine: Engine, wheels: Wheels) {
    fun driveCar() {
        Log.d("Lloyd", "Driving car")
    }
}

      /*
        In order to create an object of car we need to create the Engine and wheel objects
        as car has a dependency on Engine and Wheels.

        Engine might also have dependency on Cylinder, piston etc
        Wheels might also have dependency on Tyres, Rims etc

        So we end up creating many objects in order to create a car object

        val engine = Engine()
        val wheels = Wheels()
        val car = Car(engine, wheels)
        car.driveCar()
