locks的实现类: java.lang.Object -->java.util.concurrent.locks.ReentrantLock类一个可重入的互斥锁 Lock,替代synchronized,比synchronized有更强大的功能 -->Java.util.concurrent.locks.ReadWriteLock 提供了一对可供读写并发的锁。 使用新的锁完成生产者消费者模型: 代码如下: 仓库类(资源) class ResourceNew{ ...

wait与notify是java同步机制中重要的组成部分。结合与synchronized关键字使用,可以建立很多优秀的同步模型。 synchronized(this){}等价与public synchronized void method(){...} 同步分为类级别和对象级别,分别对应着类锁和对象锁。类锁是每个类只有一个,如果static的方法被synchronized关键字修饰,则在这个方法被执行前...

Java线程中sleep和wait两个方法常被混淆，实际在功能、使用场景、底层机制上存在本质差异。理解这些区别能避免多线程编程中锁冲突、资源竞争等问题，提升代码稳定性和执行效率。从所属类看，sleep是Thread类静态方法，直接通过Thread.sleep()调用；wait是Object类实例方法，必须由对象实例调用，比如object.wait()。这意味...
