实验4：抽象工厂模式

本次实验属于模仿型实验，通过本次实验学生将掌握以下内容：

1、理解抽象工厂模式的动机，掌握该模式的结构；

2、能够利用抽象工厂模式解决实际问题。

 

[实验任务一]：人与肤色

使用抽象工厂模式，完成下述产品等级结构：

 

 

实验要求：

 

 

源代码

package org.example;

// 抽象产品A：Person
abstract class Person {
    abstract String getMalePerson();
    abstract String getFemalePerson();
}

// 具体产品A1：AsianPerson
class AsianPerson extends Person {
    @Override
        String  getMalePerson() {
        return "男性";
    }
    @Override
    String  getFemalePerson() {
        return "女性";
    }
}

// 具体产品A2：AfricanPerson
class AfricanPerson extends Person {
    @Override
    String  getMalePerson() {
        return "男性";
    }

    @Override
    String getFemalePerson() {
        return "女性";
    }
}
class EuropePerson extends Person {
    @Override
    String  getMalePerson() {
        return "男性";
    }

    @Override
    String getFemalePerson() {
        return "女性";
    }
}

// 抽象产品B：SkinColor
abstract class SkinColor {
    abstract String getColor();
}

// 具体产品B1：AsianSkinColor
class AsianSkinColor extends SkinColor {
    @Override
    String getColor() {
        return "Yellow"; // 简化表示，实际情况可能更复杂
    }
}

// 具体产品B2：AfricanSkinColor
class AfricanSkinColor extends SkinColor {
    @Override
    String getColor() {
        return "Black"; // 简化表示，实际情况可能更复杂
    }
}
class EuropeSkinColor extends SkinColor {
    @Override
    String getColor() {
        return "White"; // 简化表示，实际情况可能更复杂
    }
}
// 抽象工厂：PersonFactory
interface PersonFactory {
    Person createPerson();
    SkinColor createSkinColor();
}

// 具体工厂1：AsianFactory
class AsianFactory implements PersonFactory {
    @Override
    public Person createPerson() {
        return new AsianPerson();
    }

    @Override
    public SkinColor createSkinColor() {
        return new AsianSkinColor();
    }
}

// 具体工厂2：AfricanFactory
class AfricanFactory implements PersonFactory {
    @Override
    public Person createPerson() {
        return new AfricanPerson();
    }

    @Override
    public SkinColor createSkinColor() {
        return new AfricanSkinColor();
    }
}
class EuropeFactory implements PersonFactory {
    @Override
    public Person createPerson() {
        return new EuropePerson();
    }

    @Override
    public SkinColor createSkinColor() {
        return new EuropeSkinColor();
    }
}
// 客户端代码
public class Client {
    public static void main(String[] args) {
        PersonFactory factory;

        // 使用亚洲工厂创建亚洲人及其肤色
        factory = new AsianFactory();
        Person asianPerson = factory.createPerson();
        SkinColor asianSkinColor = factory.createSkinColor();
        System.out.println("亚洲"+asianPerson.getMalePerson()+"性肤色: " + asianSkinColor.getColor());
        System.out.println("亚洲"+asianPerson.getFemalePerson()+"性肤色: " + asianSkinColor.getColor());
        // 使用非洲工厂创建非洲人及其肤色
        factory = new AfricanFactory();
        Person africanPerson = factory.createPerson();
        SkinColor africanSkinColor = factory.createSkinColor();
        System.out.println("非洲"+africanPerson.getMalePerson()+"性肤色: " + africanSkinColor.getColor());
        System.out.println("非洲"+africanPerson.getFemalePerson()+"性肤色: " + africanSkinColor.getColor());
        factory =new EuropeFactory();
        Person EuropePerson = factory.createPerson();
        SkinColor EuropeSkinColor = factory.createSkinColor();
        System.out.println("欧洲"+EuropePerson.getMalePerson()+"性肤色: " + EuropeSkinColor.getColor());
        System.out.println("欧洲"+EuropePerson.getFemalePerson()+"性肤色: " + EuropeSkinColor.getColor());
    }
