Writing clean code with modern Java

Recent releases of Java introduced a set of features aimed at providing better developer experience when it comes to writing code. In this live-coding session, we’ll explore several new language features and APIs enabling us to create cleaner code.

We’ll use JShell, Java’s REPL implementation from Java 9, and an excellent tool for learning and exploration of APIs, to demonstrate how the recent releases of Java allow us to produce cleaner code faster by exploring smaller, often overlooked features in Java 9-12. We’ll take a look at enhanced Collections API, extended streams, updates to Optional, try with effectively final resources, private methods in interfaces, switch expressions, local variable type inference, and more. We’ll also talk about best practices and patterns for using these features in the context of modern applications.
