将抽象和实现分离,提高了系统的灵活性，使系统进行分层，从而产生更好的系统结构。

public abstract class Corp2 {private Product product;public Corp2(Product product){this.product = product;}public void makeMoney(){this.product.beProducted();this.product.beSelled();}}

public abstract class Product {public abstract void beProducted();public abstract void beSelled();}

public class HouseCorp extends Corp2{ public HouseCorp(House house){ super(house); } public void makeMoney(){ super.makeMoney(); System.out.println("房地产公司赚大钱了..."); }}

public class House extends Product{@Overridepublic void beProducted() {System.out.println("生产出的房子是这样的...");}@Overridepublic void beSelled() {System.out.println("生产出的房子卖出了...");}}

//山寨公司public class CopycatCorp extends Corp2{public CopycatCorp(Product product) {super(product); }public void makeMoney(){super.makeMoney();System.out.println("我赚钱...");} }

public class Ipod extends Product{@Overridepublic void beProducted() {System.out.println("产出的iPod 是这样的...");}@Overridepublic void beSelled() {System.out.println("生产出的iPod卖出去了...");}}

public class Client2 {Corp2 hc = null;House house = null;public  void main() {house = new House(); //产品Ipod i = new Ipod();hc = new HouseCorp(house);//公司需要产品hc.makeMoney(); // 执行}public static void main(String[] args) {new Client2().main();}}
