You've been using the Java 8 features for quite a while and you became fluent with Lambdas and Stream API. Bravo! But you feel there's a lot more to Functional Programming than just transforming items or grouping them. You think you could do much more with passing functions in and out of your own code.
In this 2 hours hands-on course, you’ll be introduced to the advanced best practices and the functional design patterns available to us starting with Java 8. We will discuss the tradeoffs of each while we brainstorm a series of more advanced exercises.
Agenda
- Clean Code Rules in Functional Programming
- The Loan Functional Design Pattern
- Using Optional in API design
- Replace switch on enums with the Lightweight Strategy Pattern
- Working around checked exceptions with Lombok, jOOL and the Try Monad from Vavr
- Advanced Techniques: currying and partial functions
- Debugging Streams
- Streaming from files or database, AutoCloseable Streams, best practices and pitfalls
- Parallel Streams: mechanics, performance, best practices, pitfalls
What to expect?
The course is hands-on: most of the time is spent coding through a series of exercises, exploring alternative solutions discussing coding style and tradeoffs. Expect an intense brainstorming experience, extremely time-efficient.
This Training is for you because:
- You are a Java developer with solid hands-on experience in Java 8 or later
- You want to design code making full use of the functional capabilities of Java
- You want to understand how to think in Functional Programming style
Prerequisites:
- Practical experience with Java Streams and Lambdas is recommended.
Technical Requirements
To solve the exercises yourself, you will need a Java 8+ SDK installed (latest Oracle JDK will do), a decent IDE (preferably IntelliJ Community or Ultimate), and access to GitHub and Maven Central.
Optional Prep
If you want to get the best value out of this workshop, you can prepare by following the Functional Programming Essentials module.
