Learning Object-Oriented Design & Programming
In software engineering, design patterns describe how to solve recurring design problems to design flexible and reusable object-oriented software.
w3sDesign presents the up-to-date version of the well-known GoF¹ design patterns in a compact and memory friendly way so that they can be learned and memorized as fast as possible.
New design patterns that are widely used today but not included in the original twenty-three GoF design patterns will be added. This release starts with the Dependency Injection design pattern, and others will follow in next releases.
By working through individual

Simple, ready-to-run code samples show how to implement design patterns by using object-oriented programming languages such as Java.
At w3sDesign you will find all you need to know, and you will get the skills that software developers need today.
It's all for free, and it's pretty fast. Enjoy it!New Edition! GoF Design Patterns Certification
