execute()是 java.util.concurrent.Executor接口中唯一的方法,JDK注释中的描述是“在未来的某一时刻执行命令command”,即向线程池中提交任务,在未来某个时刻执行,提交的任务必须实现Runnable接口,该提交方式不能获取返回值。下面是对execute()方法内部原理的分析,分析前先简单介绍线程池有哪些状态,在一系列执行过程中涉...
总之,Java的线程原理涉及线程调度、线程状态管理、线程同步和线程间通信等方面,通过操作系统的线程调度器实现并发执行,通过各种同步机制和通信机制来保证线程安全和协作。 用法 以下是Thread类最常用的一些方法: public synchronized void start(): 启动线程,使其进入可执行状态。 public final void join() throws Interr...
