How to do it...

Follow these steps to implement the example:

1. Create a class named Task that extends the Runnable interface:

        public class Task implements Runnable {

2. Declare a private ReentrantLock attribute named lock:

        private ReentrantLock lock;

3. Implement a constructor of the class:

        public Task(ReentrantLock lock) {           this.lock=lock;         }

4. Implement the run() method. Get control of the lock, put the thread to sleep for 2 seconds, and free the lock:

        @Override         public void run() {           lock.lock();           try {             TimeUnit.SECONDS.sleep(1);             lock.unlock();           } catch (InterruptedException e) {             e.printStackTrace();           }         }

5. Create the main class of the example by creating a class named Main with a main() method:

        public class Main {  public static ...
