Java’s garbage collector has made life so easy for us developers that we sometimes confuse between deleting a reference, i.e. a task the GC does, and releasing a resource – a task the GC doesn’t do. That’s because the GC does something else for us called object finalization, [...]]]> http://chaoticjava.com/posts/simple-solution-to-resource-collection/feed/ 8 http://chaoticjava.com/posts/the-quiet-revolution-part-i-jsr-296/ http://chaoticjava.com/posts/the-quiet-revolution-part-i-jsr-296/#comments Fri, 02 Jan 2009 18:32:16 +0000 Aviad http://chaoticjava.com/?p=261 http://chaoticjava.com/posts/the-quiet-revolution-part-i-jsr-296/feed/ 4 http://chaoticjava.com/posts/jsr-292-first-draft-review/ http://chaoticjava.com/posts/jsr-292-first-draft-review/#comments Fri, 19 Dec 2008 18:51:08 +0000 Aviad http://chaoticjava.com/?p=249 http://chaoticjava.com/posts/jsr-292-first-draft-review/feed/ 2 http://chaoticjava.com/posts/giving-a-break-for-cleaner-code/ http://chaoticjava.com/posts/giving-a-break-for-cleaner-code/#comments Thu, 01 May 2008 05:42:35 +0000 Aviad http://chaoticjava.com/?p=226 dzone_url = "http://chaoticjava.com/posts/giving-a-break-for-cleaner-code/";Time for some refreshing the memory with a Java language feature probably few use, and maybe for a good reason. Suppose you’re running code on elements of an array up until a certain element is found. When your code finds that element, it stops the iteration. Therefore, your code might look like the following: for [...]]]> http://chaoticjava.com/posts/giving-a-break-for-cleaner-code/feed/ 0 http://chaoticjava.com/posts/who-wants-indexer-as-the-next-eod-feature/ http://chaoticjava.com/posts/who-wants-indexer-as-the-next-eod-feature/#comments Wed, 05 Dec 2007 07:00:34 +0000 Aviad http://chaoticjava.com/posts/who-wants-indexer-as-the-next-eod-feature/ dzone_url = "http://chaoticjava.com/posts/who-wants-indexer-as-the-next-eod-feature/";We all know the Java Collections Framework – Collection, List, Set, Map are used in almost every Java application. We also know that operator overloading in not available in Java, something that has caused a huge debate over the years, especially after C# came out and had it as a feature.

I’m not talking about the majority of data in a database, just the little bits that help the application start itself. As an example, a distributed tax calculation application, where [...]]]> http://chaoticjava.com/posts/out-of-the-box-database-notifications-jmx-and-derby-in-java-6/feed/ 2 http://chaoticjava.com/posts/can-someone-please-explain-type-inference-to-me/ http://chaoticjava.com/posts/can-someone-please-explain-type-inference-to-me/#comments Wed, 26 Sep 2007 21:43:28 +0000 Aviad http://chaoticjava.com/posts/can-someone-please-explain-type-inference-to-me/ dzone_url = "http://chaoticjava.com/posts/can-someone-please-explain-type-inference-to-me/";Not that I don’t understand the idea. It’s simple: final map := new HashMap<String,List<Thing>>(); is equal to final HashMap<String,List<Thing>> map = new HashMap<String,List<Thing>>(); And who really wants that kind of line in their code, eh? Why write things twice, anyway?

On the latter I will not remark; but regarding a comparison, let’s make a fair comparison between the two (considering, of course, that [...]]]> http://chaoticjava.com/posts/i-say-delegates-shmelegates-delegates-vs-closures/feed/ 3 http://chaoticjava.com/posts/sending-events-using-closures/ http://chaoticjava.com/posts/sending-events-using-closures/#comments Sun, 23 Sep 2007 21:00:36 +0000 Aviad http://chaoticjava.com/posts/sending-events-using-closures/ dzone_url = "http://chaoticjava.com/posts/sending-events-using-closures/";At the end of the day, closures are function pointers. However, it’s not really clear how already-defined methods on classes could be assigned to a closure. For example, suppose I have the function-type { => double }, and I want to assign to it the method double getVat()? But suppose it is possible, and I [...]]]> http://chaoticjava.com/posts/sending-events-using-closures/feed/ 4 http://chaoticjava.com/posts/why-not-notnull/ http://chaoticjava.com/posts/why-not-notnull/#comments Sat, 22 Sep 2007 17:10:02 +0000 Aviad http://chaoticjava.com/posts/why-not-notnull/ dzone_url = "http://chaoticjava.com/posts/why-not-notnull/";I’ve been reading this post, which eventually led me to this JDK7 proposal.
