Java ConcurrentLinkedQueue.peek() is a method in the Java ConcurrentLinkedQueue class that retrieves, but does not remove, the head of the queue. It is a non-blocking operation that allows for inspecting the first element in a thread-safe manner. Introduced in Java 2004 with Java 5, peek() is particularly useful in concurrent systems that require safe access to elements at the head of the queue without affecting other threads.
