The Java Workshop

4 (2)
By: David Cuartielles, Andreas Göransson, Eric Foster-Johnson

Overview of this book

Java is a versatile, popular programming language used across a wide range of industries. Learning how to write effective Java code can take your career to the next level, and The Java Workshop will help you do just that. This book is designed to take the pain out of Java coding and teach you everything you need to know to be productive in building real-world software. The Workshop starts by showing you how to use classes, methods, and the built-in Collections API to manipulate data structures effortlessly. You’ll dive right into learning about object-oriented programming by creating classes and interfaces and making use of inheritance and polymorphism. After learning how to handle exceptions, you’ll study the modules, packages, and libraries that help you organize your code. As you progress, you’ll discover how to connect to external databases and web servers, work with regular expressions, and write unit tests to validate your code. You’ll also be introduced to functional programming and see how to implement it using lambda functions. By the end of this Workshop, you’ll be well-versed with key Java concepts and have the knowledge and confidence to tackle your own ambitious projects with Java.

Introduction

The Reactive Streams specification presents an ongoing development within software architecture, referred to as Reactive Systems. These systems, ideally, have the following advantages:

  • A faster response
  • More controlled responses in relation to one another
  • Increased reliability

A natively supported API for developing Reactive Systems or applications was introduced in Java 9, called Flow.

The Java 9 Flow API was not intended to compete with the already developed, highly adopted, and appreciated reactive libraries or APIs available out there. The biggest reason for the advent of the Flow API was the need for a common denominator amongst these libraries; to ensure that the core of reactive programming would be the same regardless of which implementation you use. That way, you can easily translate from one implementation to another.

To achieve this, the Java Flow API adheres to the Reactive Streams specification—the specification that most...
