Java Functional Programming Course

Learn how to use the Java Functional Programming idioms, for writing highly maintainable and performant code

Overview

The course teaches the principles of Functional Programming in Java. It focuses on the usage and benefits of Functional Interfaces, the Optional class and the Streams API, for writing cleaner, more efficient and maintainable code.

Through a series of hands-on examples and practical exercises, the participants will learn how to apply each individual Functional Programming technique and to combine them cohesively.

Objectives

By the end of the course, the participants will:

  • Understand the core concepts of Functional Programming in Java
  • Use Functional Interfaces to write lambda expressions and method references
  • Use the Optional class to handle null values more elegantly and more efficiently
  • Apply the Streams API for processing collections of data
  • Integrate the Functional Programming techniques and idioms in new and existing Java projects

Duration and Schedule

The minimum course duration is 2 days, 6 or 7 hours per day. If possible, we highly recommend a longer duration, to allow more time for hands-on work and refactoring existing projects to incorporate Functional Programming idioms.

Each course session will be composed of a theoretical and a practical part. The ratio between the theoretical and practical components will vary depending on:

  • The complexity of the discussed topic
  • The questions and discussions related to it
  • The participant's interest in that topic

Target Audience

The course is ideal for Java developers who want to:

  • Improve their understanding and usage of Functional Programming
  • Enhance their code quality and productivity
  • Refactor existing code to use the Functional Programming idioms

Prerequisites

The course participants:

  • Must be proficient in Java programming, especially using Object-Oriented Programming concepts
  • Must have the desire to learn new programming concepts and practices
  • Should know high-level software design guidelines, especially:
    • Separation of Concerns
    • Single Responsibility Principle

Testimonials

We really enjoyed Bogdan's training sessions. It's always cool to learn and have fun while doing them. He is very patient and always prepared to offer the best solution/explanation for any problem/question. ... I also love his ability to extend the context for each chapter, offering many smart hooks to integrate the concept in a broader picture, which makes it all easier to understand.

Sorin, Crossover

Bogdan is our coach who helped shape our vision to use Java and Spring/SpringBoot in today's marketplace. He is highly skilled, extremely passionate and has a strong work ethic. With his unique and practical approach, he taught us from technology fundamentals on up to software design and best practices. He is continuously helping us progress on a growing path in software development. I enjoy working with Bogdan very much and I consider him a friend.

Andrei, Óce

When we approached Bogdan for a Java training, our goal was to up-skill our team of PL/SQL developers in order to become proficient in Java. [...] Bogdan has vast experience in the topics and very good communication and presentation skills. The pace was very good and he was very thorough in responding all questions, providing lots of related documentation for further study.

Radu, Nokia

Working with Bogdan is really inspiring and I always learn something new from his training and coaching sessions. All the training sessions are well-structured, use examples and employ hands-on components. What I enjoyed most during his training sessions is that they made me eager to learn more and to extend my knowledge. And it's not hard to do, thanks to the documentation that Bogdan provides for further reading.

Corina, Cerner

For a year and a half I've participated in various courses held by Bogdan, from Java 8, Spring, Maven to Docker. He has a good methodology, a strong background, he keeps you interested and he is open for discussions even after the training sessions, which is very important. Usually we have more questions after we start using the knowledge from the courses.

Ion, Sociéte Générale

I have participated in several training sessions held by Bogdan, including Java 8, Maven, CI & CD, Git and Spring. Every time we were thrilled to discover the information and best practices described, especially as he exemplified them with many hands-on examples. Furthermore, there were a few things present in each session that defined Bogdan's approach, namely, professionalism, vast knowledge and experience, innovative solutions, a great personality and a sense of humor.

Lavinia, Elysian

I am the self-learning type; I usually get bored at every course/training, very quickly. With this course, it was not the case. I payed attention ~95% of the time, which is very rare for me.

Ionuț, Nokia

I was pleasantly surprised by this course, being probably much more than other courses that can be found online. The presentation is very good, the materials are well structured and prepared, with many examples. Moreover, I consider the context information to be welcome, some of it was not very "settled" for me, such as the information about the application architecture, etc. Another plus regarding the training and the trainer is the fact that I managed to pay attention approximately 99% of the time, which I find amazing.
