1.抽象工厂方法模式：为了创建一组或相互依赖的对象提供一个接口，而不需要指定它们是具体类……无语

2.找个代码看看：

 抽象工厂类<成员为接口>

 

/** * 抽象工厂 * */public abstract class Factory {    public abstract A CreateA();    public abstract B CreateB();}

接口A

public interface  A {    void aa();}

接口B

public interface B {    void bb();}

A的实例

public class One_A implements A {    @Override    public void aa() {        System.out.println("***:One_A");    }}

public class Two_A implements A {    @Override    public void aa() {        System.out.println("***:Two_A");    }}

B的实例

public class One_B implements B {    @Override    public void bb() {        System.out.println("***:One_B");    }}

public class Two_B implements B {    @Override    public void bb() {        System.out.println("***:Two_B");    }}

Factory实例

public class A_Factory extends Factory {    @Override    public A CreateA() {        return new One_A();    }    @Override    public B CreateB() {        return new One_B();    }}

public class B_Factory extends Factory {    @Override    public A CreateA() {        return new One_A();    }    @Override    public B CreateB() {        return new Two_B();    }}

实现：

Factory factory=new A_Factory();        factory.CreateA().aa();        factory.CreateB().bb();        Factory factory1=new B_Factory();        factory1.CreateA().aa();        factory1.CreateB().bb();
