Gateway Software Symposium
March 6 - 8, 2009 - St. Louis, MO
Java Concurrency Idioms
This presentation will look at the many new additions in Java 5 and 6 for concurrent programming such as Atomics, Locks, synchronizers, and concurrent collections. In particular, we will be looking at common concurrency idioms around locking and access to shared state, thread coordination, thread pooling, and work execution. Each of these topics will be presented with code examples demonstrating common idioms and the usage of these new concurrency primitives.
Some topics we will cover in detail include: * Thread coordination with Thread.join(), CountdownLatch, and CyclicBarrier * Access to shared state with synchronized, volatile, Atomics, Lock, ReadWriteLock * Using Locks and Conditions to achieve more flexibility than synchronized and wait/notify * Concurrent collections like ConcurrentHashMap, CopyOnWriteArrayList, and ConcurrentSkipListMap * Work execution with Queues, ThreadPools, and Executors
