• Java Stream
• ThreadLocal
• PipedStream
• JMH
• Disruptor
• FutureTask
• java.util.concurrent
• 线程通信
  • 共享变量
  • wait(), notify()实现生产和消费通知
• 同步线程
  • wait(), sleep(), notify(), notifyAll()
• Timer

  • class MyTask extends java.util.TimerTask{
        @Override
        public void run() {
            // TODO Auto-generated method stub
            System.out.println("________");
        }
    }
    Timer timer = new Timer()
    timer.schedule(new MyTask(), 1000, 2000)    // 1秒后执行，每两秒执行一次
    timer.cancel();     // 停止任务

• Thread
  • currentThread().getContextClassLoader().getResource(”/“).getPath() # 静态路径
  • run()
  • start()
  • sleep() # 占有锁
  • 异常抛出不到父线程

    • new Thread(){
          @Override
          public void run(){
              while(count > 0){
                  synchronized(AboutThread.class){

                  }
              }
          }
      }.start();
