Chapter 8. Simplifying Bean Development with BeanUtils

The preceding chapters dealt with tools that are external to the program being developed. These tools are meant to simplify the development of a program and verification of the program’s correctness. We now turn to tools that are incorporated into programs being developed. These tools solve common problems and reduce the quantity and complexity of code that must be written.

One very common problem is the issue of hierarchical data. This problem takes many forms, such as a network of nested beans, an XML document, or several tables in a database with one-to-many or many-to-many relationships. In all these cases the common feature is that one object may have many connections to other objects, ...
