public class BaoMaTyre implements Tyre{private String name=null;public BaoMaTyre(String name) {this.name=name;}@Overridepublic void tyre() {System.out.println(name+"的轮胎");}

方向盘接口与具体实现：

/*** 方向盘接口* @author Linhai Gu**/
public interface SteeringWhell {public void steeringWhell();
}

public class AoDiSteeringWhell implements SteeringWhell{private String name=null;public AoDiSteeringWhell(String name) {this.name=name;}@Overridepublic void steeringWhell() {System.out.println(name+"的方向盘");}}

public class BaoMaSteeringWhell implements SteeringWhell{private String name=null;public BaoMaSteeringWhell(String name) {this.name=name;}@Overridepublic void steeringWhell() {System.out.println(name+"的方向盘");}
}

抽象工厂类：

public interface AbstractFactory {/** 创建Motor对象*/public Motor creatMotor();/** 创建Tyre对象*/public Tyre  creatTyre();/** 创建SteeringWhell对象*/public SteeringWhell creatSteeringWhell();}

实现类：

public class AoDiFactory implements AbstractFactory{@Overridepublic Motor creatMotor() {// TODO Auto-generated method stubreturn new AoDiMotor("奥迪");}@Overridepublic Tyre creatTyre() {// TODO Auto-generated method stubreturn new AoDiTyre("奥迪");}@Overridepublic SteeringWhell creatSteeringWhell() {// TODO Auto-generated method stubreturn new AoDiSteeringWhell("奥迪");}}

public class BaoMaFactory implements AbstractFactory{@Overridepublic Motor creatMotor() {// TODO Auto-generated method stubreturn new BaoMaMotor("宝马");}@Overridepublic Tyre creatTyre() {// TODO Auto-generated method stubreturn new BaoMaTyre("宝马");}@Overridepublic SteeringWhell creatSteeringWhell() {// TODO Auto-generated method stubreturn new BaoMaSteeringWhell("宝马");}}

品牌厂家制造车类：

</pre><pre name="code" class="java">public class CarEngineer {//车需要的发动机private Motor motor=null;//车需要的轮胎private Tyre tyre=null;//车需要的方向盘private SteeringWhell steeringWhell=null;public void makeCar(AbstractFactory af){this.motor=af.creatMotor();this.tyre=af.creatTyre();this.steeringWhell=af.creatSteeringWhell();this.motor.motor();this.tyre.tyre();this.steeringWhell.steeringWhell();}}

测试：

public class Test {public static void main(String[] args) {// TODO Auto-generated method stub//品牌厂家CarEngineer carEngineer=new CarEngineer();//客户1选的牌子AbstractFactory aoDi=new AoDiFactory();//客户2选的牌子AbstractFactory baoMa=new BaoMaFactory();//厂家推出System.out.println("客户1:");carEngineer.makeCar(aoDi);System.out.println("客户2:");carEngineer.makeCar(baoMa);}}

运行结果：
