Running unit tests ensures the particular functionality works as expected, and running integration tests ensures the state of data in an end-to-end flow context of the application remains intact. However, running consecutive sequences of tests would alter the data state between tests, to ensure fair and accurate execution of all tests the data for the tests should be baselined to an a

Using DelayQueue instead of BlockingQueue, offering to the queue after the delay lapse  2. DateTimeFormatter returning strings like 'in the morning' and 'in the afternoon  3. StampedLock instead of ReadWriteLock and optimistic ReentrantReadWriteLock  4. Concurrent Accumulators instead of AtomicXXX references for concurrent updates without locks  5. Hex format  6. BinarySearch in Arrays of sorted ordering returning found value else the nearest occurrence for insertion  7. BitSet instead of a boolean array to operate the bits for and, or, xor operations  8. Phaser instead of CountDownLatch to a
