In every other value it should be false. I tried these: String value = "false"; System.out.println("test1: " + Boolean.parseBoolean(value)); System.out.println("test2: " + B...

This is to be certain that the compiler level is set correctly in Eclipse 3.5 running with Java 6 installed, but where the result needs to run on a Java 5 installation. For java 1.4 I could use "...

Effective Java, along with other sources suggest that we should consider using composition over inheritance. I have often found my self achieving such composition by using the Decorator pattern and implementing forwarding methods that delegate invocations to a wrapped object. However, I often find myself writing many simple forwarding ...
Hi, I was looking for a list of changes in the API between java 1.5 and 1.6, but I couldn't find it. I need cause I used 1.6 for development and sometimes the code needs to be deployed to server that has only 1.5, and I need to check if I've used some new features (e.g. String.isEmpty and similar). Besides just checking if the code work...

My application is mostly Java but, for certain calculations, uses a C++ library. Our environment is Java 1.6 running on RedHat 3 (soon to be RedHat 5). My problem is that the C++ library is not thread-safe. To work around this, we run multiple, single-threaded "worker" processes and give them work to do from a central Work Manager, also...
I have written quite a few Mock objects using EasyMock. However, often i find writing partial mocks time consuming, and it does not feel 'right'. I'd say its a design fault as my class I try to mock has multiple concerns into one, therefore I should create seperate classes in order to seperate concerns. What do you think? Is partially ...
