Structuring concurrent applications in JDK 5.0

JDK 5.0 is a huge step forward in developing concurrent Java classes and applications, providing a rich set of high-level concurrency building blocks.

Prior to the release of JDK 5.0, the Java platform provided basic primitives for writing concurrent programs, but they were just that – primitive – and difficult to use properly. Building multithreaded applications on the Java platform's low-level concurrency primitives posed many traps for the unwary, and many developers were forced to reinvent the wheel by writing their own classes for thread pools, semaphores, and task schedulers.

To help users create robust, scalable, and (most importantly) correct multithreaded applications, JDK 5.0 includes a rich set of high-level concurrency constructs, such as thread pools, semaphores, mutexes, barriers, and high-performance concurrent collection classes. Using these concurrency utilities will, in most cases, make your programs clearer, shorter, faster, easier to write, and more reliable. This session provides you with an overview of the new high-level concurrency utilities in the new java.util.concurrent package in JDK 5.0.
