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；

3.注意编程规范。

    }

    public String getHarddisk() {

        return harddisk;

    }

    public void setHarddisk(String harddisk) {

        this.harddisk = harddisk;

    }

    

    

 

}

 

ComputerBuilder.java

        System.out.println("台式机硬盘");

    }

    public void buildHost() {

        System.out.println("台式机主机");

    }

}

    }

}

 

Client

public class Client

{

    public static void main(String args[])

    {

        

        ComputerBuilder cb=(ComputerBuilder)XMLUtil.getBean();

        

        ComputerFactory cf=new ComputerFactory();

       

        cf.setComputerBuilder(cb);

        

        Computer c=cf.construct();

       

    }

}
