java并发分段锁实践代码
以下是代码:
packagecn.study.concurrency.ch11; /** *锁分段 *@authorxiaof * */ publicclassStripedMap{ //同步策略:就是对数组进行分段上锁,n个节点用n%LOCKS锁保护 privatestaticfinalintN_LOCKS=16; privatefinalNode[]buckets; privatefinalObject[]locks; privatestaticclassNode { privateStringname; privateNodenext; privateStringkey; privateStringvalue; publicStringgetValue(){ returnvalue; } publicvoidsetValue(Stringvalue){ this.value=value; } publicStringgetName(){ returnname; } publicvoidsetName(Stringname){ this.name=name; } publicNodegetNext(){ returnnext; } publicvoidsetNext(Nodenext){ this.next=next; } publicStringgetKey(){ returnkey; } publicvoidsetKey(Stringkey){ this.key=key; } } publicStripedMap(intnumBuckets) { buckets=newNode[numBuckets]; //创建对应hash的锁 locks=newObject[N_LOCKS]; for(inti=0;i以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持毛票票。
