Mastering Object-oriented Programming in Java 8

This course will teach you important techniques of object-oriented design that help develop highly flexible and maintainable designs, even in the most complex business domains. Your code will never look the same again after watching this course.

Procedural implementation is hurting flexibility and maintainability of code to such an extent that further development often becomes nearly impossible. In this course, Mastering Object-oriented Programming in Java 8, you’ll develop skills to help you design truly object-oriented code when modeling complex and convoluted business logic. First, you’ll learn the power of streams as a replacement for explicit loops and branching, and how they can be turned more readable and easier to manage. Next, you’ll discover the realm of fluent interface designs, that will help construct composable domain-related code. Finally, you'll explore alternatives to hard-coded decisions with the Rules design pattern. By the end of this course, you will gain insight on how rules can become composable and flexible, taming even the scariest pieces of domain logic.
