ArrayBlockingQueue is a bounded, blocking queue that stores the elements internally in an array.
That it is bounded means that it cannot store unlimited amounts of elements. There is an upper bound on the
number of elements it can store at the same time. You set the upper bound at instantiation time, and after that
it cannot be changed.
ArrayBlockingQueue stores the elements internally in FIFO (First In, First Out) order.
head of the queue is the element which has been in queue the longest time, and the
tail of the queue is the element which has been in the queue the shortest time.
Here is how to instantiate and use an
BlockingQueue queue = new ArrayBlockingQueue(1024); queue.put("1"); Object object = queue.take();
Here is a
BlockingQueue example that uses Java Generics. Notice how
you can put and take String's instead of :
BlockingQueue<String> queue = new ArrayBlockingQueue<String>(1024); queue.put("1"); String string = queue.take();
