What queues do you know for working with multithreading?

In Java, various implementations of the Queue interface from the java.util.concurrent package are often used for multithreading. Here are the main ones:

• ConcurrentLinkedQueue — a non-blocking linked list-based queue suitable for high-performance scenarios with many threads.

• LinkedBlockingQueue — a blocking queue with an optional size limit, supporting put/take operations with waiting.

• ArrayBlockingQueue — a blocking queue with a fixed size based on an array, providing FIFO order.

• PriorityBlockingQueue — a blocking queue with element priority.

• SynchronousQueue — a queue without an internal buffer, where each put blocks until another thread performs a take.

The choice depends on requirements for locking, performance, and queue semantics. For example, for size-limited tasks with thread blocking, it is better to use LinkedBlockingQueue or ArrayBlockingQueue.
