General Coding Approach and Conventions

The Java and C++ code presented in this book uses object-oriented techniques. The DOM and all its various parts are object-oriented, as are the Java file operations and the C++ file operations. (I have chosen to use the C++ classes instead of the old-style C libraries.) That said, most of what we programmers really care about is procedural in nature, that is, the code that lives and works inside methods. We care most about how to call methods that manipulate DOM objects. We don't care as much about everything else.

I have not gone out of my way to make this code object-oriented. In the beginning it is fairly simple and not necessarily very heavily object-oriented. However, as the design progresses and matures ...
