Before Java SE 8, anonymous classes were typically used to pass functionality to a method. This practice obfuscated source code, making it harder to understand. Java 8 eliminated this problem by introducing lambdas. This tutorial first introduces the lambda language feature, then provides a more detailed introduction to functional programming with lambda expressions along with target types. You’ll also learn how lambdas interact with scopes, local variables, the this and super keywords, and Java exceptions. 

Note that code examples in this tutorial are compatible with JDK 12.

The fast, lightweight, open source Quarkus Java stack will graduate from its current beta designation and become available as a production release at the end of November. Sponsored by Red Hat, the microservices-oriented Java stack supports both reactive and imperative programming models. 

Quarkus is a Kubernetes-native Java stack for cloud-native and serverless application development. Quarkus promises faster startup times and lower memory consumption than traditional Java-based microservices frameworks. It features a reactive core based on Vert.x, a toolkit for building reactive applications based on the JVM, and the ability to automatically reflect code changes in running applications.
