Is it possible to combine 3 .properties files into one .properties file?
<p>I have 3 .properties files for one application. Each file is for the Development, Test, and Production environment.  Is it possible (and practical) to combine these three files into one file? How can it be done?  Or is it best to keep each file in its own environment?  Here is the code.</p>
