　　学习设计模式的几点说明：1）应用场景；2）UML类图；3）代码。
　　关于工厂模式中简单工厂代码。 package test6.simpleFactory; import org.junit.Test; abstract class Car { public abstract void printName(); } class BenzCar extends Car { @Override public void printName() { System.out.println("Benz Car..."); } } class BMWCar extends Car { @Override public void printName() { System.out.println("BMW Car..."); } } class CarFactory { public static final int BENZ_CAR = 1; public static final int BMW_CAR = 2; public static Car createCarFactor(int type) { if(type == CarFactory.BENZ_CAR) { return new BenzCar(); } else if (type == CarFactory.BMW_CAR) { return new BMWCar(); } return null; } } public class Application { @Test public void test() { Car car = CarFactory.createCarFactor(CarFactory.BENZ_CAR); car.printName(); car = CarFactory.createCarFactor(CarFactory.BMW_CAR); car.printName(); } }
