Why, you might wonder, and I don’t have a good reason to give other than the illusion the Java Logger package gives as being more standard. I would like to stress the word illusion for a [...]]]> http://chaoticjava.com/posts/java-logger-memory-leaks/feed/ 13 http://chaoticjava.com/posts/io-performance-tar-file-bytes/ http://chaoticjava.com/posts/io-performance-tar-file-bytes/#comments Sat, 06 Dec 2008 23:12:48 +0000 Aviad http://chaoticjava.com/?p=240 dzone_url = "http://chaoticjava.com/posts/io-performance-tar-file-bytes/";One of the most classic patterns in software is the producer-consumer pattern. There is a module producing data, and a module reading it for further processing. Moreover, in order to achieve better performance, usually there are many consumer modules running on many different threads while the producer (or several producers) run on its own thread.

This post will be devoted to that subject, with some of the questions asked brought into highlight and answered using a lot of information coming from a [...]]]> http://chaoticjava.com/posts/gc-tips-and-memory-leaks/feed/ 13 http://chaoticjava.com/posts/nio-data-flow-made-resource-efficient/ http://chaoticjava.com/posts/nio-data-flow-made-resource-efficient/#comments Tue, 22 Jan 2008 09:27:40 +0000 Aviad http://chaoticjava.com/posts/nio-data-flow-made-resource-efficient/ dzone_url = "http://chaoticjava.com/posts/nio-data-flow-made-resource-efficient/";This post is all about data flow in the “New I/O” framework. The data flow mechanism in NIO is essentially different from the “old” IO. There are no decorators to data, and the entire framework revolves around getting one thing done, and done really well: transferring data from an external source into the application or [...]]]> http://chaoticjava.com/posts/nio-data-flow-made-resource-efficient/feed/ 5 http://chaoticjava.com/posts/parallel-and-concurrent-garbage-collectors/ http://chaoticjava.com/posts/parallel-and-concurrent-garbage-collectors/#comments Tue, 08 Jan 2008 06:13:12 +0000 Aviad http://chaoticjava.com/posts/parallel-and-concurrent-garbage-collectors/ dzone_url = "http://chaoticjava.com/posts/parallel-and-concurrent-garbage-collectors/";In the last post, I’ve been talking about the basics of garbage collection and the generational garbage collector. While the generational garbage collector brought huge performance benefits by getting the large, old generation memory area to be infrequently visited by the collector, it still wasn’t enough for the new era of faster processors and memory [...]]]> http://chaoticjava.com/posts/parallel-and-concurrent-garbage-collectors/feed/ 14 http://chaoticjava.com/posts/how-does-garbage-collection-work/ http://chaoticjava.com/posts/how-does-garbage-collection-work/#comments Wed, 02 Jan 2008 06:05:19 +0000 Aviad http://chaoticjava.com/posts/how-does-garbage-collection-work/ dzone_url = "http://chaoticjava.com/posts/how-does-garbage-collection-work/";It seems to me that the importance of garbage collection in Java (and other garbage collected languages) is disproportional to the explanations given about it. While there would be millions of articles when you look for JavaFX examples, there would be only a couple if you tried to search about the “Parallel Compacting Collector” mentioned [...]]]> http://chaoticjava.com/posts/how-does-garbage-collection-work/feed/ 63 http://chaoticjava.com/posts/autoboxing-tips/ http://chaoticjava.com/posts/autoboxing-tips/#comments Sun, 26 Feb 2006 22:21:49 +0000 Aviad http://javachaos.crazyredpanda.com/?p=138 dzone_url = "http://chaoticjava.com/posts/autoboxing-tips/";Autoboxing, a feature which seems like it had squeezed into JSR 201, is a convenience feature which has its own bag of tricks. This feature seems to come as a complement to the major EoD feature in Tiger, Generics. Since generics can’t be used with primitives as their types (i.e. Can’t declare Collection<int>), their wrappers [...]]]> http://chaoticjava.com/posts/autoboxing-tips/feed/ 7 http://chaoticjava.com/posts/stringbuilder-vs-string/ http://chaoticjava.com/posts/stringbuilder-vs-string/#comments Thu, 16 Feb 2006 07:30:17 +0000 Aviad http://javachaos.crazyredpanda.com/?p=131 dzone_url = "http://chaoticjava.com/posts/stringbuilder-vs-string/";A lot has been said, written and blogged on this subject, I know. I’ll try to cover it from the disassembly angle, though, after going over the main points of this comparison. Why use StringBuilder? A good question deserves a good answer.

I didn’t until a few days ago, and it’s a shame, in my opinion. In Java 5.0, we were introduced with a new feature which was the new String.format method, with the complimentary PrintStream.printf method (classically used via the System.out member). This feature allowed us to [...]]]> http://chaoticjava.com/posts/the-hardly-known-messageformat/feed/ 8
