Lock vs Synchronized Keyword

The Advantage of using Lock is that tryLock() is there to try to get the Lock if available, also with defined time to try to acquire lock before giving up

as;

 private final Lock queueLock = new ReentrantLock();

      queueLock.lock();
      try {
queueLock.tryLock(2, TimeUnit.SECONDS);
} catch (InterruptedException e) {
System.out.println(" Unable to acquire Lock");
e.printStackTrace();
}
