实验5：建造者模式

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、理解建造者模式的动机，掌握该模式的结构；

2、能够利用建造者模式解决实际问题。

 

[实验任务一]：计算机组装

使用建造者模式，完成下述任务：计算机组装工厂可以将CPU、内存、硬盘、主机等硬件设备组装在一起构成计算机，计算机的类型可以是笔记本，也可以是台式机。

实验要求：

1.  画出对应的类图；

 

2.  提交源代码；

public abstract class Builder {

    Computer computer = new Computer();

    abstract public void buildZhuJi();

        comptureKind.buildCpu();

        comptureKind.buildYinPan();

        comptureKind.buildNeiCun();

        return comptureKind.getCompture();

    }

}

    }

} 

package com.hua.sjms;

    @Override

    public void buildZhuJi() {

        computer.setZhuJi("武极");

    }

    @Override

    public void buildYinPan() {

        computer.setYinPan("512G");

    }

    @Override

    public void buildCpu() {

        computer.setCpu("因特尔");

    }

    @Override

    public void buildNeiCun() {

        computer.setNeiCun("16G");

    }

} 

package com.hua.sjms;

public class TaiShiBuilder extends Builder{

    @Override

    public void buildZhuJi() {

        computer.setZhuJi("联想");

    }

    @Override

    public void buildYinPan() {

        computer.setYinPan("1T");

    }

    @Override

    public void buildCpu() {

        computer.setCpu("英伟达");

    }

    @Override

    public void buildNeiCun() {

        computer.setNeiCun("16G");

    }

} 

package com.hua.sjms;

public class Client {

    public static void main(String[] args) {

        Builder lap;

        Creator factory=new Creator();

        for (int i = 0; i < 2; i++) {

            if(i==1) {

                System.out.println("笔记本配置如下");

                lap = new LapBuilder();

            }

            else {

                System.out.println("台式机配置如下");

                lap = new TaiShiBuilder();

            }

            factory.setCompture(lap);

            factory.construct();

            System.out.println("CPU："+lap.getCompture().getCpu());

            System.out.println("内存："+lap.getCompture().getNeiCun());

            System.out.println("硬盘："+lap.getCompture().getYinPan());

            System.out.println("主机："+lap.getCompture().getZhuJi());

        }

    }

}

3.注意编程规范。
