上类图；学习抽象工厂模式之前需要先了解简单工厂模式和工厂方法模式

这里写图片描述
- Fruit.java

package com.dyx.design.abstractfactory;public interface Fruit {    public void getFruit();}

Apple.java

package com.dyx.design.abstractfactory;public abstract class Apple implements Fruit{    public abstract void getFruit();}

Banana.java

package com.dyx.design.abstractfactory;public abstract class Banana implements Fruit {    public abstract void getFruit();}

NorthApple.java

package com.dyx.design.abstractfactory;public class NorthApple extends Apple {    @Override    public void getFruit() {            System.out.println("采集北方苹果");    }}

NorthBanana.java

package com.dyx.design.abstractfactory;public class NorthBanana extends Banana {    @Override    public void getFruit() {        System.out.println("采集北方香蕉");    }}

SouthApple.java

package com.dyx.design.abstractfactory;public class SouthApple extends Apple {    @Override    public void getFruit() {            System.out.println("采集南方苹果");    }}

SouthBanana .java

package com.dyx.design.abstractfactory;public class SouthBanana extends Banana {    @Override    public void getFruit() {        System.out.println("采集南方香蕉");    }}

FruitFactory.java

package com.dyx.design.abstractfactory;public interface FruitFactory {    public Fruit getApple();    public Fruit getBanana();}

NorthFruitFactory.java

package com.dyx.design.abstractfactory;/** * 描述： 北方产水果的工厂 */public class NorthFruitFactory implements FruitFactory {    @Override    public Fruit getApple() {        return new NorthApple();    }    @Override    public Fruit getBanana() {        return new NorthBanana();    }}

SouthFruitFactory .java

package com.dyx.design.abstractfactory;/** * 描述： 南方产水果的工厂 */public class SouthFruitFactory implements FruitFactory {    @Override    public Fruit getApple() {        return new SouthApple();    }    @Override    public Fruit getBanana() {        return new SouthBanana();    }}

运行

package com.dyx.design.abstractfactory;public class MainClass {    public static void main(String[] args) {        FruitFactory southFactory = new SouthFruitFactory();        Fruit apple = southFactory.getApple();        Fruit banana = southFactory.getBanana();        apple.getFruit();        banana.getFruit();    }}
