（3）设计模式之抽象工厂模式(创建型模式)_抽象工厂模式属于创建型设计模式。桥接模式属于结构型设计模式。-优快云博客

本文通过具体实例详细介绍了抽象工厂模式的实现方式，包括定义了Fruit接口及其实现类Apple和Banana，进一步实现了NorthApple、NorthBanana、SouthApple和SouthBanana等具体产品，并创建了NorthFruitFactory和SouthFruitFactory两个工厂类来生产不同地区的水果。

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();
    }
}
