抽象工厂模式

定义
起源与以前对不同操作系统的图形化解决方案，如不同操作系统的按钮和文本框控件其实现不同，展示效果也不一样，对于每一个操作系统，其本身就构成一个产品类，而按钮与文本框控件也构成一个类，两种产品类两种变化，各自有自己的特性。
魏传建一组相关或者是互相依赖的对象提供统一接口，而不需要指定它们的具体类。
使用场景
Android、iOS、Windows Phone下都有短信软件和拨号软件，两者都属于Software范畴，但是，他们所在的操作系统平台不一样，即便是同一家公司出品的软件，其代码的实现逻辑也是不同的。

代码
CarFactory.java

public abstract class CarFactory {    public abstract ITire createTire();    public abstract IEngine createEngine();    public abstract IBrake createBrake();}

ITire.java

public interface ITire {    void tire();}

NormalTire

public class NormalTire implements ITire {    @Override    public void tire(){        System.out.println("普通轮胎");    }}

IEngine.java

public interface IEngine {    void engine();}

ImportEngine.java

public class ImportEngine implements IEngine {    @Override    public void engine(){        System.out.println("进口发动机");    }}

DomesticEngine.java

public class DomesticEngine implements IEngine {    @Override    public void engine(){        System.out.println("国产发动机");    }}

IBrake.java

public interface IBrake {    void brake();}

SeniorBrake.java

public class SeniorBrake implements IBrake {    @Override    public void brake(){        System.out.println("高级制动");    }}

Q3Factory.java

public class Q3Factory extends CarFactory {    @Override    public ITire createTire(){        return new NormalTire();    }    @Override    public IEngine createEngine(){        return new DomesticEngine();    }    @Override    public IBrake createBrake(){        return new NormalBrake();    }}

Q7Factory.java

public class Q7Factory extends CarFactory{    @Override    public ITire createTire(){        return new SUVTire();    }    @Override    public IEngine createEngine(){        return new ImportEngine();    }    @Override    public IBrake createBrake(){        return new SeniorBrake();    }}

SUVTire.java

public class SUVTire implements ITire {    @Override    public void tire(){        System.out.println("越野轮胎");    }}

Client.java

public class Client {    public static void main(String[] args){        CarFactory factoryQ3=new Q3Factory();        factoryQ3.createTire().tire();        factoryQ3.createEngine().engine();        factoryQ3.createBrake().brake();        System.out.println("-----------------------");        CarFactory factoryQ7=new Q7Factory();        factoryQ7.createTire().tire();        factoryQ7.createEngine().engine();        factoryQ7.createBrake().brake();    }}
