Where is the Queue class in the Java Collections?

I only see a Queue interface, is there no Queue class in the Java Collections?

Answer 1

All Known Implementing Classes:

AbstractQueue, ArrayBlockingQueue, ArrayDeque, ConcurrentLinkedQueue, DelayQueue, LinkedBlockingQueue, LinkedBlockingDeque, LinkedList, PriorityBlockingQueue, PriorityQueue, SynchronousQueue
