Getting your program code to the point that it satisfies the functional requirements provided is a milestone for developers, one that hopefully brings satisfaction and a sense of accomplishment. If that code must be executed on a schedule perhaps for … Continue reading
While we lamented how feature-poor Java 7 turned out to be, one thing that made it that turns out to be a boon to high-performance concurrent development is the new Fork/Join framework. This framework is targeted at multi-processor systems (really … Continue reading
Some concurrency utilities in Java naturally get more attention than others just because they serve general purpose problems instead of more specific ones. Most of us encounter things like executor services and concurrent collections fairly often. Other utilities are less … Continue reading
As discussed in Part 3, the thread pools introduced in Java 1.5 provided core support that was quickly a favourite of many java developers. Internally, the implementations make smart use of another concurrency feature introduced in java 1.5 – Blocking … Continue reading
One of the beautiful things about Java from its very first release was the ease with which we could write multi-threaded programs and introduce asynchronous processing into our designs. The Thread class and Runnable interface combined with Java’s memory management … Continue reading
One of the most generally useful concurrency enhancements delivered in Java 1.5 was the introduction of customizable thread pools. These thread pools give you quite a bit of control over things such as number of threads, reuse of threads, scheduling … Continue reading
Java’s synchronized keyword is a wonderful tool – it allows us a simple and reliable way to synchronize access to critical sections and it’s not too hard to understand. But sometimes we need more control over synchronization. Either we need … Continue reading
This is the first part in a series that we’re going to be doing on Java concurrency. Specifically, we are going to dive into the concurrency tools built into Java 1.5 and beyond. We’re going to assume you have a … Continue reading
