线程池常见方法

如何获取线程池对象

缓存线程池

自定义任务对象

public class MyRunnable implements Runnable{private int id;public MyRunnable(int id) {this.id = id;}@Overridepublic void run() {String name = Thread.currentThread().getName();System.out.println("线程" + name + "开始执行任务" + id);try {Thread.sleep(200);} catch (InterruptedException e) {e.printStackTrace();}System.out.println("线程" + name + "完成任务" + id);}@Overridepublic String toString() {return "MyTask{" +"id=" + id +'}';}
}

获取线程池对象

 ExecutorService cachedThreadPool = Executors.newCachedThreadPool();for (int i = 0; i < 100; i++) {MyRunnable myRunnable = new MyRunnable(i);cachedThreadPool.execute(myRunnable);}
