工厂方法模式✅

工厂方法是定义一个用于创建对象的接口,让子类决定实例化哪一个类。工厂方法将一个类的实例化延迟到其子类。

适配器模式（Adapter）包含以下主要角色：

抽象产品类：RAM 、CPU

具体产品类：PcRAM、MacRAM、 PcCPU、 MacCPU

抽象工厂类： ComputerAccessoriesFactory

具体工厂类：PcFactory、 MacFactory

一、实验要求

使使用工厂方法模式实现下面描述的功能：
“电脑配件生产工厂生产内存、CPU等硬件设备，这些内存、CPU的品牌、其型号并不一定相同。”

根据下面的“产品等级结构-产品族”示意图，使用抽象工厂模式实现电脑配件生产过程并绘制相应的类图，
并运用面向对象编程语言实现该模式。

二、代码✅

package abs;

public interface ComputerAccessoriesFactory {
    CPU produceCPU();
    RAM produceRAM();
}
public interface CPU {
    void discribe();
}
public class MacCPU implements CPU {
    public void discribe()
    {
        System.out.println("This is produce the MacCPU");
    }
}
public class MacFactory implements ComputerAccessoriesFactory{

    public MacCPU produceCPU() {
        System.out.println("PC_CPU produced! >_<");
        return new MacCPU();
    }

    public MacRAM produceRAM() {
        System.out.println("PC_RAM produced! >_<");
        return new MacRAM();
    }
}
public class MacRAM implements RAM {
    public void discribe() {
        System.out.println("This is produce the MacRAM ");
    }
}
public class PcCPU implements CPU
{
    public void discribe()
    {
        System.out.println("This is produce the PC_CPU");
    }
}
public  class PcFactory implements ComputerAccessoriesFactory
{
    public PcCPU produceCPU() {
        System.out.println("PC_CPU produced! >_<");
        return new PcCPU();
    }

    public PcRAM produceRAM() {
        System.out.println("PC_RAM produced! >_<");
        return new PcRAM();
    }
}
public class PcRAM implements RAM
{
    public void discribe() {
        System.out.println("This is produce the PC_RAM ");
    }
}

    void discribe();
}
public class MacFactory implements ComputerAccessoriesFactory{

        System.out.println("PC_CPU produced! >_<");
        return new MacCPU();
    }

    public MacRAM produceRAM() {
        System.out.println("PC_RAM produced! >_<");
        return new MacRAM();
    }
}

public class MainClass {
    public static void main(String[] args) {
        ComputerAccessoriesFactory a = new PcFactory();
        ComputerAccessoriesFactory b = new MacFactory();
        ComputerAccessoriesFactory c = new MacFactory();
        ComputerAccessoriesFactory d = new PcFactory();
        CPU cpu = a.produceCPU();
        RAM ram = b.produceRAM();
        CPU cpu1 = c.produceCPU();
        RAM ram1 =d.produceRAM();
        cpu.discribe();
        ram.discribe();
        cpu1.discribe();
        ram1.discribe();
    }
