Course Description

Course Overview
This course provides a comprehensive overview of Design Patterns in Java from a practical perspective. This course in particular covers patterns with the use of:

The latest versions of the Java programming language
Use of modern programming approaches: dependency injection, reactive programming and more
Use of modern developer tools such as IntelliJ IDEA
Discussions of pattern variations and alternative approaches

This course provides an overview of all the Gang of Four (GoF) design patterns as outlined in their seminal book, together with modern-day variations, adjustments, discussions of intrinsic use of patterns in the language.
What are Design Patterns?
Design Patterns are reusable solutions to common programming problems. They were popularized with the 1994 book Design Patterns: Elements of Reusable Object-Oriented Software by Erich Gamma, John Vlissides, Ralph Johnson and Richard Helm (who are commonly known as a Gang of Four, hence the GoF acronym).
The original book was written using C++ and Smalltalk as examples, but since then, design patterns have been adapted to every programming language imaginable: C#, Java, PHP and even programming languages that aren't strictly object-oriented, such as JavaScript.
The appeal of design patterns is immortal: we see them in libraries, some of them are intrinsic in programming languages, and you probably use them on a daily basis even if you don't realize they are there.
What Patterns Does This Course Cover?
This course covers all the GoF design patterns. In fact, here's the full list of what is covered:

SOLID Design Principles: Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle and Dependency Inversion Principle
Creational Design Patterns: Builder, Factories (Factory Method and Abstract Factory), Prototype and Singleton
Structrural Design Patterns: Adapter, Bridge, Composite, Decorator, Faade, Flyweight and Proxy
Behavioral Design Patterns: Chain of Responsibility, Command, Interpreter, Iterator, Mediator, Memento, Null Object, Observer, State, Strategy, Template Method and Visitor

Who Is the Course For?
This course is for Java developers who want to see not just textbook examples of design patterns, but also the different variations and tricks that can be applied to implement design patterns in a modern way. For example, the use of recursive generics helps us build fluent interfaces even when inheritance is involved.
Presentation Style
This course is presented as a (very large) series of live demonstrations being done in IntelliJ IDEA and presented using the Kinetica rendering engine. Kinetica removes the visual clutter of the IDE, making you focus on code, which is rendered perfectly, whether you are watching the course on a big screen or a mobile phone.
Most demos are single-file, so you can download the file attached to the lesson and run it in IntelliJ, Eclipse or another IDE of your choice.
This course does not use UML class diagrams; all of demos are live coding. I use IntelliJ and various Maven packages where necessary.Who this course is for:

Software engineers
Designers
Architects

Learning new things. Teaching with examples rather than just slides makes it much easier to understand as well.

By Selvakumar on 11/7/2020

Examples are very complex to understand.

By Emil Andrag on 10/20/2020

I love the presentation, but I type very slow.

By Sunil Sharma on 10/20/2020

This is indeed a very good design pattern course as it explains GoF's idea of Design Patterns nicely.

By Karan Bhange on 10/16/2020

I like the way everything is summarised in each section. Very useful for quick revision.

Great!

By Danylo Gurianov on 10/2/2020

This is my 5th course about design patterns and 1st one after which i remeber them by heart and understand the reasons why they were created. Despite a bit overcomplicated examples , this course is above all my expectations. Thank you , Dmitri!
