一.Java中的ThreadPoolExecutor类
java.uitl.concurrent.ThreadPoolExecutor类是线程池中最核心的一个类,因此如果要透彻地了解Java中的线程池,必须先了解这个类。下面我们来看一下ThreadPoolExecutor类的具体实现源码。
在ThreadPoolExecutor类中提供了四个构造方法:
publicclassThreadPoolExecutor extends AbstractExecutorService {
publicThreadPoolExecutor(intcorePoolSize,intmaximumPoolSize,longkeepAliveTime,TimeUnit unit,
BlockingQueue workQueue);
publicThreadPoolExecutor(intcorePoolSize,intmaximumPoolSize,longkeepAliveTime,TimeUnit unit,
BlockingQueue workQueue,ThreadFactory threadFactory);
publicThreadPoolExecutor(intcorePoolSize,intmaximumPoolSize,longkeepAliveTime,TimeUnit unit,
BlockingQueue workQueue,RejectedExecutionHandler handler);
publicThreadPoolExecutor(intcorePoolSize,intmaximumPoolSize,longkeepAliveTime,TimeUnit unit,
BlockingQueue workQueue,ThreadFactory threadFactory,RejectedExecutionHandler handler);
...
}
