Subscriber是一个抽象类，提供观察员界面
因为Subscription接口方法已经由Subscriber实现，所以只需要实现ObserverT接口
@ overridepublicfinalvoidunsubscribe ) { subscriptions.unsubscribe )； }/* * * indicateswhetherthissubscriberhasunsubscribedfromitslistofsubscriptions.* * @ return { @ code true } ifthisssubscribribribstions { @ code false } otherwise */@ overridepublicfinalbooleanisunsubscribed }请看我们的演示
subscriberstringmysubscriber=newsubscriberstring { @ overridepublicvoidonnext strings ) system.out.println ) ) s ) } @ overridepublicvoidoncompleted { } @ overridepublicvoidonerror ) throwablee ) }；
