• 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

- 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();
    }
}
