Creating a Manager for Multiple Threads 1.You should also read Processes and Threads The previous lesson showed how to define a task that executes on a separate thread. If you only want to run the task once, this may be all you need. If you want to r
private ThreadFactory threadFactory = new ThreadFactoryBuilder().setNameFormat("billService-pool-%d").build(); private final ExecutorService pool = new ThreadPoolExecutor(20, 20,0L, TimeUnit.MILLISECONDS,new LinkedBlockingQueue<Runnable>(5
Java thread pool manages the pool of worker threads, it contains a queue that keeps tasks waiting to get executed. We can use ThreadPoolExecutor to create thread pool in java. Java thread pool manages the collection of Runnable threads and worker thr
Understanding concurrent programming is on the same order of difficulty as understanding object-oriented programming. If you apply some effort, you can fathom the basic mechanism, but it generally takes deep study and understanding to develop a true
一.认识问题: 首先我们通过下面这个 测试程序 来认识这个问题:运行的环境 (有必要说明一下,不同环境会有不同的结果):32位 Windows XP,Sun JDK 1.6.0_18, eclipse 3.4,测试程序: Java代码 import java.util.concurrent.CountDownLatch; public class TestNativeOutOfMemoryError { public static void main(String[] args) { for
