Software Architecture (SOLID) & Design Patterns in Java from Udemy

This course is about software architecture and design patterns. We will talk about two man topics: SOLID principles and design patterns. We are going to implement the problems in Java, but the theoretical background is language-independent. I highly recommend typing out the implementations several times on your own in order to get a good grasp of it.

Section 1 - SOLID Principles

what are SOLID principles?
single responsibility principle
open closed principle
Liskov's substitution principle
interface segregation principle
dependency inversion principle
what is dependency injection?

Section 3 - Creational Design Patterns

what are creational design patterns?
singleton pattern
factory pattern
abstract factory pattern
builder pattern
prototype pattern

Section 2 - Behavioral Design Patterns

what are behavioral design patterns?
strategy pattern
observer pattern
command pattern
iterator pattern
template pattern and null object pattern
visitor pattern

Section 3 - Structural Design Patterns

what are structural design patterns?
decorator pattern
flyweight pattern
facade pattern
adapter pattern

Section 4 - Model-View-Controller (MVC) Pattern

the model-view-controller (MVC) model
an application with Java Swing

In the first part of the course we are going to learn about the SOLID principles. We are going to talk about the theory as well as the implementations.

The second part of the course is about design patterns. We should have a deep understanding of these patterns in order to be able to write reusable software components. These techniques are becoming more and more important as applications are getting more and more complex, so - in my opinion - these topics are good to know.

Thank for joining the course, let's get started.
