Pain-free Functional Programming with Java 21

Explore functional programming techniques adapted for Java 21 in this 55-minute conference talk that demystifies FP concepts for Java developers. Learn how to implement battle-proven techniques from Scala and the functional programming world using modern Java features. Discover practical approaches to working with immutable values and data structures, implementing pattern matching, handling errors without traditional exceptions, and reducing dependency on injection frameworks. Master essential functional programming abstractions including product and union types, monads, and other advanced concepts that can initially seem overwhelming to object-oriented programmers. Gain hands-on insights into writing cleaner, more maintainable code by applying functional programming principles within the familiar Java ecosystem, making the transition from imperative to functional thinking both accessible and practical.
