The design patterns are language-independent strategies used to solve common object-oriented design issues (problems). When you design a problem, you should know some common solutions. It makes communication between team players easier, effective and result oriented.
A good software-developer should know at least some popular solutions to the coding problems. These solutions prove efficient and effective to the new breed of developers as they are gradually developed by the experienced developers. Such solutions are described as so-called design patterns.
Learning design patterns speeds up a developer experience in accumulating OOA/OOD concepts. Once a developer grasp them, he would be benefited from them to be a master of designing and developing. Furthermore, he will use these terms to communicate with his fellows or assessors more effectively. Design pattern is a indispensable part of Java and J2ee technologies.
Learning the design patterns is a
multiple step process:
1. Individual acceptance
2. Group/Mass recognition
