Java 101: Java concurrency without the pain, Part 2

The Java Concurrency Utilities are high-level concurrency types that facilitate threading tasks especially on multicore systems. Part 1 of this introduction featured java.util.concurrent‘s Executor framework, synchronizer types, and Java Concurrent Collections package. In Part 2, learn how the Java Concurrency Utilities handle locking, atomic variables, and fork/join operations. Then prepare for the future with an overview of seven anticipated changes to the Java Concurrency Utilities coming in Java 8.

Java’s low-level threading capabilities are famously hard to use and error-prone, which is why they’re frequently associated with deadlock, thread starvation, race conditions, and other concurrency bugs. One alternative to losing your sleep and peace of mind is the Java Concurrency Utilities, introduced in JDK 5. The two articles in this short series are dedicated to exploring how Java developers use the packages and libraries in java.util.concurrent to work around common threading bugs and write cleaner, simpler programs.
