1.1、类的适配器模式类的适配器模式核心思想就是:有一个Source类,拥有一个方法,待适配,目标接口是Targetable,通过Adapter类,将Source的功能扩展到Targetable里。同事类族:packagecom.model.behaviour;?publicabstractclassAbstractColleague{???protectedAbstractMediatormediator;????/**既然有中介者,那么每个具体同事必然要与中介者有联系,????*否则就没必要存在于这个系统当中,这里的构造函数相当????*于向该系统中注册一个中介者,以取得联系????*/??publicAbstractColleague(AbstractMediatormediator){?????this.mediator=mediator;???}????//在抽象同事类中添加用于与中介者取得联系(即注册)的方法???publicvoidsetMediator(AbstractMediatormediator){?????this.mediator=mediator;???}?}//具体同事A?packagecom.model.behaviour;?publicclassColleagueAextendsAbstractColleague{????//每个具体同事都通过父类构造函数与中介者取得联系???publicColleagueA(AbstractMediatormediator){?????super(mediator);???}????//每个具体同事必然有自己分内的事,没必要与外界相关联???publicvoidself(){?????System.out.println("同事A-->做好自己分内的事情...");???}????//每个具体同事总有需要与外界交互的操作,通过中介者来处理这些逻辑并安排工作???publicvoidout(){?????System.out.println("同事A-->请求同事B做好分内工作...");?????super.mediator.execute("ColleagueB","self");???}?}//具体同事B?packagecom.model.behaviour;?publicclassColleagueBextendsAbstractColleague{????publicColleagueB(AbstractMediatormediator){?????super(mediator);???}????publicvoidself(){?????System.out.println("同事B-->做好自己分内的事情...");???}????publicvoidout(){?????System.out.println("同事B-->请求同事A做好分内工作?...");?????super.mediator.execute("ColleagueA","self");???}?}中介者类族:packagecom.model.behaviour;?publicabstractclassAbstractMediator{????//中介者肯定需要保持有若干同事的联系方式???protectedHashtablecolleagues=newHashtable();????//中介者可以动态地与某个同事建立联系???publicvoidaddColleague(Stringname,AbstractColleaguec){?????this.colleagues.put(name,c);???}??????//中介者也可以动态地撤销与某个同事的联系???publicvoiddeleteColleague(Stringname){?????this.colleagues.remove(name);???}????//中介者必须具备在同事之间处理逻辑、分配任务、促进交流的操作???publicabstractvoidexecute(Stringname,Stringmethod);??}//具体中介者?packagecom.model.behaviour;?publicclassMediatorextendsAbstractMediator{????//中介者最重要的功能,来回奔波与各个同事之间???publicvoidexecute(Stringname,Stringmethod){??????if("self".equals(method)){?//各自做好分内事???????if("ColleagueA".equals(name)){?????????ColleagueAcolleague=(ColleagueA)super.colleagues.get("ColleagueA");?????????colleague.self();???????}else{?????????ColleagueBcolleague=(ColleagueB)super.colleagues.get("ColleagueB");?????????colleague.self();???????}?????}else{//与其他同事合作???????if("ColleagueA".equals(name)){?????????ColleagueAcolleague=(ColleagueA)super.colleagues.get("ColleagueA");?????????colleague.out();???????}else{?????????ColleagueBcolleague=(ColleagueB)super.colleagues.get("ColleagueB");?????????colleague.out();???????}?????}???}?}测试类://测试类?packagecom.model.behaviour;?publicclassClient{???publicstaticvoidmain(String[]args){??????//创建一个中介者?????AbstractMediatormediator=newMediator();??????//创建两个同事?????ColleagueAcolleagueA=newColleagueA(mediator);?????ColleagueBcolleagueB=newColleagueB(mediator);??????//中介者分别与每个同事建立联系?????mediator.addColleague("ColleagueA",colleagueA);?????mediator.addColleague("ColleagueB",colleagueB);??????//同事们开始工作?????colleagueA.self();?????colleagueA.out();?????System.out.println("======================合作愉快,任务完成!\n");??????colleagueB.self();?????colleagueB.out();?????System.out.println("======================合作愉快,任务完成!");???}?}运行结果:同事A-->做好自己分内的事情...?同事A-->请求同事B做好分内工作...?同事B-->做好自己分内的事情...?======================合作愉快,任务完成!??同事B-->做好自己分内的事情...?同事B-->请求同事A做好分内工作?...?同事A-->做好自己分内的事情...?======================合作愉快,任务完成!十一、解释器模式解释器模式:给定一种语言,定义他的文法的一种表示,并定义一个解释器,该解释器使用该表示来解释语言中句子。3LikingFit从诞生之初给自己贴上了24小时智能化健身房的标签.用户通过一个App完成购卡、购课、约课、数据同步等功能。multiprocess:多进程方式,一个进程处理一个请求。当然,选址是一个门学问,LikingFit当然不可能做到每家店都获得盈利。
