知足常乐|Java线程池原理，这一篇就够了( 二 ) 作者|remax1|简书前言线程池（ThreadPo

核心代码就从任务队列中不断取出runable对象(即MyTask)并执行。
excute()只是将任务(MyTask)加入到队列(BlockQueue)中。
//执行任务只是把任务加进任务队列，什么时候执行由线程管理器决定public void execute(Runnable task){try {taskQueue.put(task);} catch (InterruptedException e) {e.printStackTrace();}}测试代码：
public static void main(String args[]) throws InterruptedException{ThreadPool threadPool = new ThreadPool(5,100);threadPool.execute(new MyTask("testA"));threadPool.execute(new MyTask("testD"));threadPool.execute(new MyTask("testB"));threadPool.execute(new MyTask("testE"));threadPool.execute(new MyTask("testF"));System.out.println(threadPool);Thread.sleep(10000);threadPool.destroy();System.out.println(threadPool);}运行截图:
