抽象工厂模式其实是一种最一般的工厂模式形态,简单工厂模式和工厂方法模式都可以看成抽象工厂模式的特殊实现.

抽象工厂模式提供一个创建一系列相关或相互依赖对象的接口,而无需指定它们具体的类

import java.util.*;interface Ifunc1 {    public void work1_1();    public void work1_2();}interface Ifunc2 {    public void work2_1();    public void work2_2();}class ProductA1 implements Ifunc1 {    public void work1_1() {        System.out.println("ProductA1 work1_1");    }    public void work1_2() {        System.out.println("ProductA1 work1_2");    }}class ProductB1 implements Ifunc1 {    public void work1_1() {        System.out.println("ProductB1 work1_1");    }    public void work1_2() {        System.out.println("ProductB1 work1_2");     }}class ProductA2 implements Ifunc2 {    public void work2_1() {        System.out.println("ProductA2 work2_1");    }    public void work2_2() {        System.out.println("ProductA2 work2_2");    }}class ProductB2 implements Ifunc2 {    public void work2_1() {        System.out.println("ProductB2 work2_1");    }    public void work2_2() {        System.out.println("ProductB2 work2_2");     }}interface IFactory {    public Ifunc1 createIfunc1();     public Ifunc2 createIfunc2();}class ProductAFactory implements IFactory {    public Ifunc1 createIfunc1() {        return new ProductA1();    }    public Ifunc2 createIfunc2() {        return new ProductA2();    }}class ProductBFactory implements IFactory {    public Ifunc1 createIfunc1() {        return new ProductB1();    }    public Ifunc2 createIfunc2() {        return new ProductB2();    }}public class AbstractFactoryMethod {    public static void main(String[] args) {        IFactory factoryA = new ProductAFactory();         factoryA.createIfunc1().work1_1();        factoryA.createIfunc1().work1_2();    }}
