【代码积累】factory pattern without reflection

public class FactoryWithoutReflection {public static void main(String[] args) {// TODO Auto-generated method stubCar car = null;Plane plane = null;Car.register2Factory();Plane.register2Factory();car = (Car)(BigthingFactory.getInstance().createBigThing("Car"));car.print();car = (Car)BigthingFactory.getInstance().createBigThing("Car");car.print();plane = (Plane)BigthingFactory.getInstance().createBigThing("Plane");plane.print();}}
