    TS-3708(USA,2003) - Concurrency Utilities -- Multithreading Made Easy
     
    The Java[tm] platform provides basic primitives for writing concurrent programs, but they are difficult to use properly. Many programs become clearer, shorter, faster, easier to write, and more reliable if, instead of starting from scratch, you use higher-level synchronization and coordination constructs. A comprehensive library of concurrency utilities is being developed under (JSR-166) for planned inclusion in the 1.5 release of the Java[tm] 2 Platform, Standard Edition (J2SE[tm]). This library, known as util.concurrent contains thread pools, queues, concurrent collections, special-purpose locks, barriers, and related utilities. This talk provides you with all the information you need to start using this library, which is already available in preliminary form.
