Object[] toArray(): Returns an array containing all of the elements in this set. If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. Java Queue Basics As Java Queue extends Java Collection, ...
Yes, a queue can be implemented using an array. In such an implementation, the rear of the queue is associated with the end of the array, and the front is associated with the beginning. However, it is important to handle cases of overflow (when the queue is full) and underflow (when ...

Java Queue represents an ordered list of elements. Java Queue follows FIFO order to insert and remove it’s elements. FIFO stands for First In First Out. Java Queue supports all methods of Collection interface. Most frequently used Queue implementations are LinkedList, ArrayBlockingQueue and Priorit...
Java ArrayBlockingQueue example. ArrayBlockingQueue is concurrent and bounded blocking queue implementation backed by an array. It orders elements in FIFO.
