BlockingQueueimplementations are thread-safe. All queuing methods achieve their effects atomically using internal locks or other forms of concurrency control. However, thebulkCollection operationsaddAll,containsAll,retainAllandremoveAllarenotnecessarily performed atomically unless specified otherwise in an implemen...
Java Queue interface extends Collection interface. Collection interface extends Iterable interface. Some of the frequently used Queue implementation classes are LinkedList, PriorityQueue, ArrayBlockingQueue, DelayQueue, LinkedBlockingQueue, PriorityBlockingQueue etc.. AbstractQueue provides a skeletal implementation...

This code utilizes a LinkedList as the underlying data structure and produces a Queue named bank queue. Customers are added to the end of the line using the add method, and customers are removed from the line using the remove method so that the person in front of them may be served. Befo...
