Course Description

From this course, you can learn Software Architecture and Clean Code Design in OOP.

There are a lot of other courses on this topic. So, why would you choose exactly this course?  Here are just a few reasons:

- Coding examples

To learn to program is not enough just watching videos and reading books. You also need to have a lot of practice. In this training course, you will review multiple practical tasks and coding examples which will help you learn and understand Java better.


- Open source code

We hide nothing from our students! Including the source code for the home task solutions and source code of examples that were shared during the lesson. Having the source code you can just copy and paste it to run it on your local computer to understand how things work better.

You are allowed to use all source code examples for learning purposes. This helps significantly to configure the environment and make tests work, especially in case students didn't work with any testing framework in the past.

- Q&A support 

The significant difference between the online and offline learning process is the instructor's availability. If you are in one room with a tutor he always can help you to get understand the specific concept or to help fix your code on your computer.
In this course, we are supporting students with answers to any questions flagged in the Q&A section. In case there will be recurring questions - separate video lessons will be created to show how to address the issue.

So with this course you are not just getting video materials, code exercises, source code, access to the free mobile application without limits (which is still pretty cool, huh? :) ), but you also get tutor support and answers to your questions along with this course.

- Relevant knowledge

After our team investigated other Java courses on Udemy we realized that most of them have nothing in common with real life. The information which is shared there is very old and significantly out of date. For example, the instructor teaches a framework which is not been used already for 15 years. Or instructors do stress on the programming design which is not used anymore at all!

The instructor of this course is a consultant in a top-rated IT outsourcing company and helps to bring cutting-edge solutions in IT for all his clients. Feel free to check the LinkedIn page of the instructor and check skills endorsement. More than 19 thousand people across all over the world (BTW most of them are from the top 100 companies of the world) evaluated the skills of Andrii Piatakha.

With this course, you can be sure that you will spend your time learning the right things from one of the best IT consultants in the world.

- Free mobile App without limits for our students

Knowing Java is one skill. Be able to pass interviews in the company - that is another skill :) Nowadays a lot of companies use tests to select candidates on the first level of interview. We developed applications to practice skills specifically for such purposes.

In this course, we will provide you link to download our FREE mobile app for android. (soon it will be also available for iOS platforms)

The instructor of this course comes up with hundreds of tests that are used to test the knowledge of candidates. With this application, you will be well-prepared for the interview.

Also, only for our students - there is no limit on attempts to pass certification. In the course, we will tell you how to set up a special bonus code that will remove restrictions for our students inside the app.

- High concentration of useful material in each lesson

Sometimes you can notice that watching 5 minutes of our lesson is equivalent to watching another 30 minutes lesson.

This is because time spent for preparation for the lesson (script for the lesson, lesson structure) and video editing (to cut boring pieces of the lesson or time when the program loads) sometimes 10 times as much (sometimes even 20) as the final lesson duration after video editing.

Also, each topic is separated from another. In case some concept will be explained in the next lesson and you don't need to worry about understanding this in the scope of this lesson - the instructor will make an announcement when a specific topic will be covered.

Go and try it yourself! We will appreciate your feedback.

So far, all it seems fine I will need attend the next courses to get a best criteria about the whole course

By Joana Sousa on 1/23/2026

Overall a very good course if you want to learn everything more in detail. Perhaps too many details were taught in the course, but I can always come back to check on them whenever in doubt

By Amin Mohabbat on 10/6/2023

This course will be better with more advanced example for Golf Design Patterns. Because some of these patterns, need to be used in advanced problem or example to more understandable

By Charl Du Plessis on 6/26/2023

The sample modules are excellent, allows you to try it yourself and then check your code against the completed code.

By Harold Johan Castillo Obando on 2/24/2023

Thank you for sharing with us this useful information, as a feedback, I felt in some parts that you read from your notes and this sometimes makes me lose interest in what you present, specifically, when you were talking about design patterns; however, it does not take away the good work and effort you put into it.

By Anica on 3/7/2022

So far I really like it. It explains things that I found confusing in a simple way with actual code examples and real-life coding problems.

By Denys Malik on 1/15/2022

Great course. It is well-structured and has a big amount of practice. I've got a lot of useful info from it. Thank you.

By Alejandro Toro Ossaba on 1/12/2022

The course has a lot of valuable information and useful techniques for clean programming, however, the explanations are a little bit redundant, making the lessons long, also the programming examples are explained very fast. In the database section there are references to other lessons that are not included in the course which creates some confusion. Also the course is definitely not for all levels, it is necesary a clear understanding of object oriented programing principles and some basic knowledge in java or at leat a similar programming language.

By Mishell Yagual on 9/29/2021

Buen complemento para el conocimiento general que se sabe tener de POO.

By Hoang Truong Minh on 8/15/2021
