异步的几种方式

目录

• 继承Thread

• 使用Runnable

• 使用Callable和FutureTask

• 使用Callable、FutureTask和线程池

继承Thread

    Thread t = new Thread() {
        @Override
        public void run() {
            // ...
        }
    };
    t.start();

使用Runnable

    Thread t = new Thread(new Runnable() {
        @Override
        public void run() {
            // ...
        }
    });
    t.start();

使用Callable和FutureTask

    Callable<String> callable = new Callable<String>() {
        @Override
        public String call() {
            return "Hello Callable!!!";
        }
    };
    FutureTask<String> futureTask = new FutureTask<>(callable);
    Thread t = new Thread(futureTask);
    t.start();

使用Callable、FutureTask和线程池

    Callable<String> callable = new Callable<String>() {
        @Override
        public String call() {
            return "Hello Callable!!!";
        }
    };
    FutureTask<String> futureTask = new FutureTask<>(callable);
    ExecutorService service = Executors.newSingleThreadExecutor();
    service.execute(futureTask);
