Design Patterns

What is a Design Pattern?

If you are here reading this post you might be looking a knowledge on Design Patterns and the first question which comes on anyone’s mind is “What is a Design Pattern?”. Lets answer this question in your own way.

You are person who know the syntax of a programming language and you are able to successfully convert any requirement into the code. One fine morning you reach office and your senior tells you about a new project requirement. You understood the requirement and have decided whats need to be done and what are the object of classes required to achieve this. But internally, whole the time from beginning to the end of the development you always know that there can be a better way to achieve this, and of course you search for other solutions to. Whatever you decide to implement you will finish off the task, but was that the best solution for the requirement? When this question comes in to you mind, the answer can be only given in terms of Design Patterns.
