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;
    }


    @Override
    public 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);
    }


    @Override
    public 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);
 }
