What is the difference between BlockingQueue and Queue in Java?

What is the difference between BlockingQueue and Queue in Java?

The main difference is that BlockingQueue supports operations that wait for the queue to become non-empty when retrieving an element, and for space to become available when adding an element.

Can you give me an example of how BlockingQueue works?

Sure! In a BlockingQueue, if a thread tries to take an element from an empty queue, it will wait until an element is available. Similarly, if a thread tries to add an element to a full queue, it will wait until space is available.

When should I use BlockingQueue instead of Queue?

You should use BlockingQueue when you need to handle producer-consumer scenarios where threads need to wait for resources to be available.

Are there different implementations of BlockingQueue?

Yes, there are several implementations like ArrayBlockingQueue, LinkedBlockingQueue, and PriorityBlockingQueue, each with different characteristics.
