Development Using Patterns
Andrew Patzer · Apress eBooks · 2004
Akey advantage to using Java technology is that it’s an OO language. This enables you to write code that’s reusable and highly scalable. As you become more accustomed to OO development, you may recognize a few best practices that you follow when developing solutions of a particular class. For instance, you may find that for every data-entry application you work on, you tend to code the data validation routines in a similar way. If you were to formalize this best practice and abstract away some of the implementation details, it’s conceivable that others could use it as a road map to jumpstart their own development efforts by implementing an already proven technique for data validation. This eliminates a lot of design effort as well as numerous testing iterations.
