You have a pool of worker thread (each worker has its own double-ended work queue) and pushes new tasks to its own queue. Then reads it from the head of the queue. If a queue is empty then a worker tries to get a task from the tail of another queue. Stealing is infrequent since...
chances of candidate answering this question satisfactory is only 50%. Half of the time, they failed to write code for double checked locking and half of the time they failed how it was broken and fixed on Java 1.5. This is actually an old way of creating thread-safe s...
Double-Dipping For an extra layer of sweetness, consider double-dipping the beans. Allow the first coating to cool before dipping again. Final Steps Once coated, place them on a parchment-lined baking sheet for drying. The end result is homemade, double-dipped, gourmet-style coffee beans! Ti...
A rich set of implementations is provided with underlying data structures (such as array lists, linked lists, or double-end queues) and concurrent behaviors (such as blocking, supporting priorities, or delays). Fine-grained specification of time-out delays, because a large portion of the ...

We can do this representing double value as raw long bits: Double.doubleToLongBits( randomValue ). Using all above, we can create an algorithm with O(N) time complexity and O(1) space complexity. public static void shuffle( int[] arr ){ checkForNull( arr ); int maxValue = arr.length...
