I wrote in my previous post about StringBuilder’s in Java, and I felt I should provide some measurements around the whole discussion. So I put together some quick and dirty code which is good enough for a comparison of the 2 ways of creating a StringBuilder — bear in mind I said “comparison”, as such […]

About Data Comparison in Java
If you have been involved in some coding (Java or otherwise) more than likely at some point you had to deal with the situation where you have to compare some data — for the purpose of sorting items in a list, of validating input, or many of the many other situations that require it. And […]
Data Validation inside a List
Felt like sharing this, since there might be some other “dinosaurs” like myself (i.e. slow in their using the Apache Commons Collections) — and those guys might find this useful 🙂 Occasionally you find yourself providing components that will be used by various modules in a project, and as such you have to employ strict […]
Neat Trick for Returning an Empty List in Java
I’ve found this post actually burried in my “Drafts” — it’s been there for sometime it seems. I recall writing about it on my mobile WordPress application, so I’m guessing I’ve saved it as draft on the blog with the view to apply the code pretty-printing and forgot about it quite likely 🙂 So I […]
Arrays in Java
I seem to be on a roll today so I thought I’d mention this little tip that I have come across in the past when using arrays — more specifically bi-dimensional arrays. We think of such arrays (in Java and other languages as well!) quite often as a bit of a Scrabble board where we […]
Apache Commons Collections
I discovered this recently myself (having not been a big fan of Apache Commons Collections in the past) — and it’s a useful feature if you are dealing with a list of objects that can be compared by more than one property. For instance, consider you have a list of Person’s (see class below) which […]
Thread Pools in Java
On the subject of Java code optimisation: I’m sure we’re all familiar with the concept of thread pooling — typically used together with the Executor framework. Configuring your thread pools can be tricky: choose a small value and you’re not making usage of your server power, on the other hand, choose a value large enough […]
Java StringBuilder
This is something that I have seen quite a few times while looking online at other people’s code so I thought I’d write about it quickly — preach the world and all that 🙂 I’m referring here to the JDK class StringBuilder, however, those of you who know your JDK classes would surely have figured […]
The Joys of Development Frameworks
I haven’t had much time lately to use my beloved mobile WordPress application – due to a mixture of owning a Kindle nowadays and being swamped with work. Ironically it was some of the recent work that forced me in the end to write this article so today I gave up my Kindle on the […]
Compilation tools
If you are developing applications as your day job then you are used more than likely to compiling your code and then running it (I know there are exceptions to the rule in those who are using interpreted languages but there’s still a majority of us it seems who use compilers). Some of you might […]
