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；

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。
