Development Using Patterns

Abstract

A key advantage to using Java technology is that it’s an Object-Oriented (OO) language. This enables you to write code that is reusable and highly scalable. As you become more accustomed to OO development, you might 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 roadmap 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.
