They can make their code more flexible, reusable and maintainable
Refactor existing designs to use design patterns
They will learn with different scenario where then can apply the design patterns for the solutions of complex problems
Reason about applicability and usability of design patterns

Course Overview:

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.

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:

Creational Design Patterns: Builder, Factories (Factory Method and Abstract Factory), Prototype and Singleton
Structural Design Patterns: Adapter, Bridge, Composite, Decorator, Façade, Flyweight ...many more.
Behavioral Design Patterns: Chain of Responsibility, Command, Interpreter, Iterator, Observer, State, Strategy and Template Method many more.

Presentation Style

This course is presented as a (very large) series of live demonstrations along with the concepts being done in Java language. Most demos are as project, so you can download the attached zipped folder of the lesson and run it in Eclipse IDE of your choice.

In the last section you will find some important points to remember always.(Rule of Thumbs).

Basic Java knowledge is required(To understand the demo code)
Good understanding of object-oriented design principles
A computer with the JDK 8 or 11 (hopefully) an Eclipse IDE
