The output confirms that there are five threads in the pool named from “pool-1-thread-1” to “pool-1-thread-5” and they are responsible to execute the submitted tasks to the pool. ThreadPoolExecutor Example Executorsclass provide simple implementation ofExecutorServiceusingThreadPoolExecutorbu...
ThreadPoolExecutor – Java Thread Pool Example Java threadpool manages the pool of worker threads, it contains a queue that keeps tasks waiting to get executed. We can useThreadPoolExecutorto create thread pool in java. Java thread pool manages the collection of Runnable threads and worker thread...

since the pool size is 5, it will start working on 5 jobs and other jobs will be in wait state, as soon as one of the job is finished, another job from the wait queue will be picked up by worker thread and get’s executed. ...

ThreadPoolExecutor – Java Thread Pool Example 一 使用线程池的好处 池化技术想必大家已经屡见不鲜了,线程池、数据库连接池、Http 连接池等等都是对这个思想的应用。池化技术的思想主要是为了减少每次获取资源的消耗,提高对资源的利用率。 线程池提供了一种限制和管理资源(包括执行一个任务)的方式。 每个线程池还...
