与接口相关的设计模式(Java).doc

与接口相关的设计模式:1. 定制服务模式2. 适配器模式3. 默认适配器模式4. 代理模式5. 标识类型模式6. 常量接口模式定制服务模式例如:某电信公司为个人用户定制的两款宽带服务套餐极速精英套餐金融专网套餐宽带上网服务(2Mbps)在线杀毒服务50MB邮箱服务付费:2999无限包年或140无限包月电信金融专网服务(1Mbps)在线杀毒服务28MB网络硬盘服务5MB邮箱服务付费:3000无限包年或150无限包月Public interface SuperSpeedCombo extends BrandBandService,VirusKillingService,MailboxServicePublic interface Financecombo extends FinancialNetworkService,VirusKillingService,MailboxService,NetworkDiskServicePayment类的源程序：Public class Payment Public static final String TYPE_PER_YEAR=”按年付费“；Public static final String TYPE_PER_MONTH=”按月付费“；Private String type;Private double price;Public Payment(String type,double price)this.type=type; This.price=price;/此处省略显示type属性和price属性的get和set方法.superSpeedComboImpl类的源程序如下：public class SuperSpeedcomboImpl implements SuperSpeedComboprivate BroadbandService broadbandService;private VirusKillingService virusKillingService;private Mailbox Service mailboxService;private Payment payment;public superSpeedcomboImpl(BroadbandService broadbandService, VirusKillingService virusKillingService, Mailbox Service mailboxService, Payment payment)this.BroadbandService= broadbandService;this.VirusKillingService= virusKillingService;this.Mailbox Service= mailboxService;this.Payment =payment;Public void connect(String username ,String password)broadbandService.connect(username,password);Public void disconnect()broadbandService.disconnect();Public void scanvirus()virusKillingService.scanVirus();Public void sendMail()mailboxService.sendMail();Public void receiveMail()mailboxService.reveiceMail();Public void deleteMail()mailboxService.deleteMail();Public Payment getPayment()Return payment;以下程序创建了极速精英套餐服务的一个实例：Payment payment=new Payment(payment TYPE_PERYEAR,2999);BroadbandService broadbandService=new BroadbandService(2);MailboxService mailboxService=new MailboxServiceImpl(50);VirusKillingService virusKillingService=new VirusKillServiceImpl();SuperSpeedCombo supe
