Factory Pattern is Creational Design pattern.Itis used when we have a parent class with multiple child classes and based on input, we need to return one of the child-class.

#Factory Class: Here is the basic implementation of Factory Class.

 public class CarFactory {
 
    public static Car getCar(Cars type) { 
       if (type == CarsConst.maruti800) {
            return new MarutiCar();
        } else if (type == CarsConst.alto) {
            return new AltoCar();
        } else if (type == CarsConst.swift){
            return new SwiftCar();
        }
        return null;
    }
}
