Explore how Java and Scala are incorporating functional programming concepts in this 50-minute conference talk from GOTO Copenhagen 2019. Dive into the journey of imperative languages adopting functional features, comparing Java's careful integration with Scala's approach. Learn about generics, type erasure, closures, lambdas, and pattern matching in both languages. Gain insights into the advantages of functional programming and how these two popular languages are evolving to combine imperative and functional paradigms. Discover the challenges and solutions in implementing features like wildcards, partial application, and inheritance in generic types. Understand the ongoing evolution of Java and Scala as they continue to learn from and adapt functional programming principles.
