What is the Java BlockingQueue interface used for?

The Java BlockingQueue interface is used for implementing a queue that supports thread-safe operations, specifically designed for inter-thread communication and synchronization. It provides methods for adding, removing, and examining elements in a blocking manner, meaning that if the queue is empty, the thread attempting to remove an element will be blocked until an element becomes available, and if the queue is full, the thread attempting to add an element will be blocked until space becomes available. This interface is commonly used in concurrent programming scenarios where multiple threads need to communicate and coordinate their actions through a shared queue.
