Pluralsight - Encapsulation and SOLID torrent

This course teaches how to write maintainable and flexible object-oriented code.

Learn how to write maintainable software that can easily respond to changing requirements using object-oriented design principles. First, you'll learn about the fundamental object-oriented design principle of Encapsulation, and then you'll learn about the five SOLID principles, also known as 'the principles of object-oriented design.' While this course is aimed at beginner to intermediate developers, it's based on decades of experience, so even advanced programmers can learn a thing or two. There are plenty of code examples along the way; while they're written in C#, they should be easily understandable to readers of Java or other curly-brace-based languages.
