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.

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

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
