Course Description
This is a course about useful clean code principles.
My aim is to teach you concepts that you can use every time you write code.
The course has Java examples and I sometimes mention things like Spring and Lombok.
The same clean code principles apply also to PHP, C# and Python.
What can this course do for you?
It can save your company and yourself a lot of development time and therefore a lot of money.
How?
Bad code practices can make development very slow on your medium and big projects.
This means a lot of money wasted on development time.
This type of projects are also remarkably unpleasant to work on.
This course helps you avoid this by using clean code principles.
The course is structured in 4 parts:
1. Introduction - where we discuss what is clean code and why it's important
2. Small Functions - I gave small functions an entire section because I think its one of the most important principles of clean code, together with small classes, Single Responsibility Principle and Not crossing Different Levels of Abstraction.
3. Clean code: Fundamental Principles - I discuss here about fundamental things like method and variables names, parameters, comments and exceptions
4. Clean code: Advanced Principles - Here I talk about more abstract topics like the difference between an OOP Object and a Data Structure Object, Composition over Inheritance, Symptoms of Bad Code, State, Low Coupling - High Cohesion, Command and Query Separation, Tell Don't Ask, The Law of Demeter and more.
The course also contains some memes because you can't spell clean code without fun.
I tried to focus on things you can use every day when programming and stay away from barren theory.
There's no point wasting our time with useless knowledge that would just seem like it's helping you as a programmer, but that you will forget in 2 weeks.
If that would have been the point, this would be a 10 hours course about programming patterns.
But it isn't.
I tried to make the course full of useful information but not too long.
If you invest as little as two hours of your life in this course, about the time you would spend watching a movie, you will become a much better developer.

Prerequisites
What are the prerequisites for this course?
You must know the basics of a programming language before taking this course.
Preferably Java, since the code examples are in Java.
