What is a BlockingQueue?

Can you explain what a BlockingQueue is?

A BlockingQueue is a type of queue that supports operations that wait for the queue to become non-empty when retrieving an element, and wait for space to become available in the queue when storing an element.

What are the main features of a BlockingQueue?

The main features include thread-safety, blocking operations for adding and removing elements, and the ability to handle producer-consumer scenarios.

Can you give me an example of how to use a BlockingQueue in Java?

Sure! In Java, you can use the ArrayBlockingQueue class. Here's a simple example:

BlockingQueue<Integer> queue = new ArrayBlockingQueue<>(10);
queue.put(1); // Adds an element, waits if necessary
Integer value = queue.take(); // Retrieves and removes the head, waits if necessary
