Learning Object-Oriented Design & Programming
The GoF Design Patterns Memory presents an up-to-date online version of the well-known GoF¹ design patterns book. All design patterns are provided in a compact and memory friendly form so that they can be studied and memorized as fast as possible.
Design patterns describe
how to solve recurring
to design flexible and reusable
By working through the Design Patterns Memory, you will learn how to design objects that are easier to implement, change (maintain), test, and reuse.
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!
