So I'm working on a project at work where I'm porting some more C++ code to Java. I looked at the original code and said, "Well, let's see if we can streamline that." And I wrote a set of classes to support the behaviors that I wanted and which would generate the XML that I needed that C++ had been handling by writing exquisitely hand-crafted XML.
And I looked at the classes and said, "That could be simpler." And so I refactored the class structure I had written.
And I looked at the classes and said, "That could really be simpler." And I refactored the class structure into a set of Java enums.
