There are a lot of other courses in this topic. So, why would you choose exactly this course? Here just a few reasons:
– Coding examples
To learn programming it 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 hometask solutions and source code of examples which 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 environment and make tests work, especially in case student didn’t work with any testing framework in the past.
– Q&A support
The significant difference between online and offline learning process is instructor’s availability. If you are in the one room with tutor he always can help you to get understanding 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 Q&A section. In case there will be recurring questions – separate video lessons will be created to show how to address issue.
So with this course you are not just getting video materials, code exercises, source code, access to 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 has nothing in common with real life. Information which is shared there is very old and significantly out of date. For example, instructor teaches framework which is not used already for 15 years. Or instructor do a stress on the programming design which is not used anymore at all!
Instructor of this course is consultant in the top-rated IT outsourcing company and helps to bring cutting-edge solutions in IT for all his clients. Feel free to check LinkedIn page of instructor and check skills endorsement. More than 19 thousand people acrooss all over the world (BTW most of them are from top 100 companies of the world) evaluated skills of Andrii Piatakha.
With this course you can be sure that you will spend your time learning the right things from the 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 interview in company – that is another skill 🙂 Nowadays a lot of companies use tests to select candidates on the first level of interview. We developed application 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)
Instructor of this course come up with hundreds tests which are used to test 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 special bonus code which will remove restrictions for our students inside the app.
– High concentration of useful material in each lesson
Sometimes you can notice that watching of 5 minutes of our lesson is equivalent to watching of other 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 program loads) sometimes 10 times as much (sometimes even 20) as 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 scope of this lesson – instructor will make announcement when specific topic will be covered.

Bonus section
Bonus lesson
- Course Overview
- Exploring the fundamental shift from tactical programming to strategic system engineering, ensuring that your code serves as a robust foundation for business growth rather than a bottleneck.
- Understanding the psychology of code maintainability and how to write logic that remains readable and intuitive for team members who may join the project years after its inception.
- Analyzing the relationship between business domain complexity and technical implementation to ensure that the software model accurately reflects real-world requirements and constraints.
- Learning how to manage the inevitable growth of technical debt by implementing proactive strategies for identifying, documenting, and resolving structural flaws before they become critical.
- Investigating the trade-offs between various development methodologies and how high-level design decisions influence the overall velocity and predictability of the software delivery lifecycle.
- Developing a “future-proof” mindset that prioritizes flexibility and extensibility, allowing systems to pivot in response to market changes without requiring a complete rewrite of the codebase.
- Focusing on the boundary between application logic and external infrastructure, ensuring that your core business rules remain isolated from volatile third-party dependencies and frameworks.
- Examining the role of the lead developer in fostering a culture of technical excellence through code reviews, shared design vocabulary, and collaborative decision-making processes.
- Mastering the art of abstraction to hide unnecessary complexity, allowing developers to focus on high-value features rather than getting bogged down in low-level implementation details.
- Evaluating the performance implications of different design choices, striking a balance between highly optimized machine code and clean, human-centric software structures.
- Implementing strategies for managing global state and side effects, leading to more deterministic and predictable application behavior across different environments.
- Requirements / Prerequisites
- A foundational understanding of object-oriented programming concepts such as classes, inheritance, and polymorphism in any modern language like Java, C#, C++, or Python.
- Basic familiarity with the software development lifecycle, including common stages such as requirement gathering, implementation, testing, and deployment to production.
- Experience in writing functional code for small to medium-sized applications, even if the structural design of those applications was not initially a primary concern.
- An open-minded approach to unlearning certain “quick and dirty” coding habits in favor of long-term sustainable practices that may initially require more upfront thought.
- Comfortable navigating an Integrated Development Environment (IDE) and performing basic version control operations like committing and branching in Git or similar tools.
- A genuine curiosity about why certain software projects succeed while others become unmanageable messes, and a desire to move from a junior to a senior engineering mindset.
- Access to a computer with a modern development environment set up to participate in practical exercises and refactoring challenges throughout the duration of the course.
- Skills Covered / Tools Used
- Advanced refactoring techniques using modern IDE tools to transform legacy “spaghetti code” into organized, clean, and highly testable software components.
- Strategic use of visual modeling languages like UML to communicate complex system structures and data flows to both technical and non-technical stakeholders effectively.
- Integrating static analysis and linting tools into the development workflow to automatically enforce coding standards and detect potential architectural violations in real-time.
- Utilizing automated testing frameworks to create a safety net for structural changes, ensuring that refactoring efforts do not introduce regressions into existing functionality.
- Managing project dependencies and versioning using package managers to maintain a clear and conflict-free environment for multi-developer collaboration on large repositories.
- Documentation strategies that go beyond simple comments, focusing on architectural decision records (ADRs) and living documentation that evolves alongside the system.
- Implementing continuous integration pipelines that validate the structural integrity of the code at every stage of the development process, from local branch to main trunk.
- Performance profiling tools used to identify bottlenecks that may arise from specific architectural choices, allowing for data-driven optimization of the software system.
- Benefits / Outcomes
- Gaining the ability to look at a complex codebase and immediately identify structural risks, allowing you to provide high-value feedback during peer code reviews.
- Significantly reducing the time spent on debugging and maintenance by creating systems where bugs are easier to isolate and fixes have fewer unintended side effects.
- Accelerating the onboarding process for new team members by providing a clear, logical, and well-documented architectural structure that is easy to navigate and understand.
- Enhancing your professional reputation as a senior engineer or architect who prioritizes quality, reliability, and long-term business value over short-term “hacks.”
- Improving team morale and job satisfaction by reducing the frustration associated with working on fragile, overly complex, or poorly designed software systems.
- Developing a universal vocabulary for software design that allows you to collaborate effectively with other professional engineers across different languages and platforms.
- Securing a competitive edge in the job market, as companies increasingly look for developers who can lead the design phase of a project rather than just follow instructions.
