The motivation behind using the abstract factory design pattern is to create objects which belong to a group, but inherit from several different base classes or implement different protocols. I learned about design patterns almost 20years ago and I've enjoyed teaching and sharing them with people ever since.

Structural Design Patterns Structural patterns provide different ways to create a class structure, for example using inheritance and composition to create a large object from small objects. Core Java Design Patterns In core java, there are mainly three types of design patterns, which are further divided into their sub-parts: 1. Over time it can become challenging to change an implementation because classes become tightly coupled. Behavioral Design Patterns Behavioral patterns provide solution for the better interaction between objects and how to provide lose coupling and flexibility to extend easily. But remember one-thing, design patterns are programming language independent strategies for solving the common object-oriented design problems.
