1、OOA&D 第六周小课题目1、民用电源为交流220V，某电器需要直流5V电源，使用适配器模式实现电源转换。对象适配器模式和类适配器模式UML如下图。分别使用对象适配器模式和类适配器模式代码实现该结构。并构造客户端类。测试适配器功能。适配器 单抽象桥接 双抽象代码：/class V220Plugpackage week06_01;public class V220Plug public void GetPower() System.out.println(Show 220 valts ac。);/class V5Plugpackage week06_01;public class V5Plug
2、public void Get5VPower() System.out.println(Show 5 valts dc。);/class ObjectAdapterpackage week06_01;public class ObjectAdapter extends V220PlugV5Plug v5 = new V5Plug();public void GetPower() v5.Get5VPower();/class My220Plugpackage week06_01;public interface My220VPlug public void GetPower();/class C
3、lassAdapterpackage week06_01;public class ClassAdapter extends V5Plug implements My220VPlugpublic void GetPower() Get5VPower();/class Clientpackage week06_01;public class Client public static void main(String args) System.out.println(ObjectAdapter:); V220Plug electrical1 = new ObjectAdapter(); elect
4、rical1.GetPower(); System.out.println(ClassAdapter:); My220VPlug electrical2 = new ClassAdapter(); electrical2.GetPower(); 运行结果：2、在三种操作平台上Windows、Linux和Mactosh绘制四种图形Rectangle、Circle、Line和Square。即在不同平台上实现画图形Shape，而shape本身也变化。使用桥接模式可以隔离抽象类的变化和实现的变化。UML类图如下，用代码实现桥接模式的应用。并构造客户端类。实现在各种平台上画出各种图形。ShapeDraw
