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 Information which is shared there is very old and significantly out of date.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.
Go and try it yourself! We will appreciate your feedback.

Course Overview
- This comprehensive course transcends mere syntax, diving deep into the philosophical underpinnings and practical application of the Gang of Four (GoF) Design Patterns.
- It’s an immersive journey designed to elevate your problem-solving abilities, guiding you through the strategic decisions that shape robust and maintainable software architectures.
- Explore how these timeless patterns serve as a universally understood language among developers, fostering unparalleled clarity in communication and collaboration within any engineering team.
- Grasp the art of identifying recurring design challenges in software development and learn to strategically deploy proven, elegant solutions that enhance modularity, flexibility, and adaptability.
- Understand the “why” behind each pattern, not just the “how,” allowing you to critically assess its suitability for various architectural contexts and avoid common anti-patterns.
- The curriculum emphasizes transforming abstract design principles into concrete, highly maintainable, and efficient Java code, bridging the gap between theoretical knowledge and practical implementation.
- Discover how mastering these patterns significantly reduces technical debt, streamlines development cycles, and ensures your software stands resilient against evolving requirements.
- Uncover the enduring relevance of these foundational patterns, demonstrating their continued importance in modern software engineering paradigms and contemporary frameworks.
Requirements / Prerequisites
- A solid, working knowledge of Java fundamentals, including core syntax, data types, control structures, and basic exception handling.
- Comfort with the fundamental concepts of Object-Oriented Programming (OOP): encapsulation, inheritance, polymorphism, and abstraction.
- Familiarity with creating and manipulating classes, objects, interfaces, and abstract classes within a Java environment.
- Basic experience using a Java Integrated Development Environment (IDE) such as IntelliJ IDEA, Eclipse, or NetBeans.
- An understanding of basic software development principles and a desire to write cleaner, more organized, and scalable code.
- No prior knowledge of design patterns is required; the course is structured to build your expertise from the ground up.
Skills Covered / Tools Used
- Strategic Problem-Solving: Develop an acute ability to diagnose complex software design problems and strategically apply appropriate, pattern-based solutions.
- Code Refactoring Expertise: Acquire the practical skills to identify opportunities for refactoring existing codebases to integrate design patterns, significantly enhancing their extensibility and reducing inherent complexity.
- Modular & Reusable Code Design: Master advanced techniques for structuring code that maximizes reusability across projects, minimizes tight coupling, and actively promotes independent, modular development.
- Architectural Communication & Documentation: Gain proficiency in articulating and documenting complex software architectures using standard design pattern terminology, drastically improving team coherence and project understanding.
- Robust System Engineering: Obtain the expertise necessary to architect and construct resilient, highly scalable, and easily maintainable software systems from their foundational components.
- Deep Object-Oriented Design (OOD) Mastery: Profoundly deepen your understanding and practical, hands-on application of sophisticated OOD principles, moving well beyond introductory theoretical concepts.
- Implementation Best Practices & Debugging: Hone your skills in diagnosing and effectively resolving issues within pattern implementations, consistently adhering to rigorous industry-standard best practices.
- Industry-Standard Java IDEs: All practical examples and exercises are conducted within widely used Java development environments (e.g., IntelliJ IDEA, Eclipse) to simulate real-world workflows.
- Software Design Heuristics: Learn to apply various design heuristics and principles, such as SOLID, to guide your pattern choices and implementations.
