There are a lot of other courses in this topic. So, why would you choose exactly this course? Here just a few reasons:
– Coding exercises
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 have different practical tasks which will help you learn and understand Java better. Beside that all topics and lessons are presented on real-life examples – this help grasp knowledge faster.
One of the key tasks where you can practice your knowledge is implementation of backend system for online store. Also you have a lot of tasks that use domain specific terminology: accounts, transactions, users, carts, menu, services etc. So that means you are learning programming without abstract concepts like it is written in the books or in other courses. You learn domain specific terminology and during the lessons we investigate specific extracts from code that can give you clear vision how you can apply the knowledge in real life.
– 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.
– 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 Information which is shared there is very old and significantly out of date.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 18 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.

Bonus Lesson
- Course Caption: Mastering Modern Java: Elevate Your Code with Functional Programming, Lambdas, and Streams for Clarity, Conciseness, and Concurrency.
Course Overview
- This immersive course introduces you to a transformative paradigm in software development: Functional Programming (FP). You’ll move beyond traditional imperative styles to embrace a declarative approach that dramatically improves code readability, maintainability, and testability. We delve deep into how FP principles, often associated with other languages, are elegantly implemented and leveraged within the Java ecosystem, revolutionizing the way you design and implement solutions.
- Explore the fundamental shift from “how to do” to “what to do,” enabling you to write more expressive and less error-prone code. This course is designed to equip you with the mindset and tools to tackle complex problems with simplicity and elegance, making your applications more robust and easier to reason about. You will learn to compose functions, avoid mutable state, and understand the power of immutability in building reliable systems.
- Uncover the incredible power of Lambda Expressions and Method References as cornerstones of modern Java. These features streamline code, reduce boilerplate, and enable a more fluent, functional style. You’ll master their syntax, best practices, and practical applications, transforming verbose anonymous inner classes into concise, understandable constructs. This simplification is key to writing cleaner, more efficient, and truly functional Java code.
- Dive into the revolutionary Stream API, Java’s declarative approach to processing collections of data. You’ll learn how to perform powerful aggregate operations like filtering, mapping, reducing, and collecting data with unparalleled expressiveness and efficiency. We’ll explore intermediate and terminal operations, understanding how they chain together to form powerful data pipelines, and even touch upon the benefits of parallel streams for leveraging multi-core processors with minimal effort.
Requirements / Prerequisites
- A solid understanding of core Java syntax and object-oriented programming (OOP) concepts is essential. This includes familiarity with classes, objects, interfaces, inheritance, polymorphism, and basic data types.
- Prior experience with data structures such as Arrays, Lists, Sets, and Maps will be beneficial, as functional programming often involves transforming and processing collections.
- Basic proficiency with an Integrated Development Environment (IDE) like IntelliJ IDEA, Eclipse, or VS Code, including setting up projects and running Java applications.
- A willingness to rethink conventional coding patterns and embrace new, more declarative approaches to problem-solving.
Skills Covered / Tools Used
- Declarative Programming Style: Develop the ability to express program logic in terms of “what” needs to be done rather than “how,” leading to more concise and understandable code.
- Higher-Order Functions: Gain expertise in passing functions as arguments and returning functions from other functions, a core FP concept enabled by Java’s functional interfaces.
- Immutability & Side-Effect Free Code: Learn to design systems that minimize mutable state, leading to more predictable behavior, easier debugging, and enhanced thread safety.
- Effective Use of Built-in Functional Interfaces: Master the application of `Predicate`, `Consumer`, `Function`, `Supplier`, `UnaryOperator`, `BinaryOperator`, and their primitive specialized versions for diverse scenarios.
- Stream Pipeline Construction: Skillfully build complex data processing pipelines using a variety of intermediate (e.g., `filter`, `map`, `flatMap`, `sorted`, `distinct`, `limit`, `skip`) and terminal (e.g., `forEach`, `reduce`, `collect`, `count`, `min`, `max`, `anyMatch`) operations.
- Concurrency with Streams: Understand the basics of leveraging parallel streams for automatic, efficient utilization of multi-core architectures without complex threading logic.
- IDE Proficiency: Practical exercises will utilize modern Java IDEs (e.g., IntelliJ IDEA, Eclipse) to write, debug, and refactor functional Java code.
