该命令可能在新的线程、已入池的线程或者正调用的线程中执行,这由 Executor 实现决定。 publicinterfaceExecutor {/*** Executes the given command at some time in the future. The command * may execute in a new thread, in a pooled thread, or in the calling * thread, at the discretion of the ...
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...
线程池简化了线程的管理工作,并且java.util.concurrent提供了一种灵活的线程池作为Executor框架的一部分。在Java类库中,任务执行的主要抽象不是THread而是Executor。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 代码6-3 Executor接口 publicinterfaceExecutor { /** * Executes the given command at some time in ...
