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：

1. 画出对应的类图；

 

 

2. 提交源代码；

BlackFactory

package abstractFactory;

public class BlackFactory extends Factory {
    @Override
    public Man produceMan() {
        return new BlackMan();
    }

    @Override
    public Woman produceWoman() {
        return new BlackWoman();
    }
}

BlackMan

package abstractFactory;

public class BlackMan extends Man{
    @Override
    public void manProduce() {
        System.out.println("生产一个黑色皮肤男人");
    }
}

BlackWoman

package abstractFactory;

public class BlackWoman extends Woman{
    @Override
    public void womanProduce() {
        System.out.println("生产一个黑色皮肤的女人");
    }
}

Client

package abstractFactory;

import java.util.Scanner;

    public static void main(String[] args) {
        System.out.println("请选择生产的人种：1：黄皮肤男人、2：黄皮肤女人、3：黑皮肤男人、4：黑皮肤女人、5：白皮肤男人、6：白皮肤女人");
        Scanner sc = new Scanner(System.in);
        int choice = sc.nextInt();
        Factory factory;
        Man man;
        Woman woman;
        if(choice == 1) {
           factory = new YellowFactory();
