ReentrantLock笔记(一) -- 基本使用

ReentrantLock基本使用

交替输出

ReentrantLock lock = new ReentrantLock(true);//true为公平锁，false或缺省为非公平锁
Runnable r = () -> {
    while (!Thread.currentThread().isInterrupted()) {
        lock.lock();
        try {
            System.out.println("当前线程：" + Thread.currentThread().getName());
            TimeUnit.SECONDS.sleep(1);
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
        } finally {
            lock.unlock();
        }
    }
};
new Thread(r).start();
Thread.sleep(10);
new Thread(r).start();
Thread.sleep(10);
new Thread(r).start();

生产者、消费者

ReentrantLock lock = new ReentrantLock();
LinkedList queue = new LinkedList
