Lightbend Java Language - Lambdas

This course introduces Lambdas and related concepts. Lambdas allow developers to write Java in a functional style.

About This Course

Java 8 introduced us to Java Lambdas. Lambdas are a way to write Java code in a more functional style. This functional style allows us to create components that are flexible and composable. It is used in Java Streams, Java CompletableFutures, and the Lightbend Ecosystem.

In this course you will learn about Functional Interfaces and how they can be converted to Java Lambdas. You will see how method references can be used to replace Lambdas where appropriate. Finally you will learn some of the best practices to follow when working with Lambdas.
