title: Conditional Java compilation
body: <p>I'm a longtime C++ programmer, new to Java. I'm developing a Java Blackberry project in Eclipse. Question - is there a way to introduce different configuration sets within the project and then compile slightly different code based on those?</p>
  
  <p>In Visual Studio, we have project configurations and #ifdef; I know there's no #ifdef in Java, but maybe something on file level?</p>
