Java 17 Recipes

 Who This Book Is For
This book is intended for anyone interested in learning the Java programming language 
and/or who already knows the language, but would like some information regarding 
Java features even if they have no experience with algorithms. Those who have not yet 
programmed in the Java language can read this book, and will allow them to get up and 
running quickly. Intermediate and advanced Java developers looking to update their 
arsenal with the latest features that Java makes available to them can also read the book 
to update and refresh their skill set. There is, of course, a myriad of other essential topics 
that will be useful to Java developers of any type.
 How This Book Is Structured
This book is structured such that it does not have to be read from cover to cover. It is 
structured so that developers can choose which topics they wish to read about and jump 
right to them. Each recipe contains a problem to solve, one or more solutions to solve 
that problem, and an explanation of how the solution works. The book is designed to 
allow developers to quickly get a solution up and running so that they can be home in 
time for dinner.

CHAPTER 1
Getting Started with 
Java 17
This chapter presents a handful of recipes to help programmers who are new to the Java 
language and those with experience in other languages become accustomed to Java 17. 
You learn to install Java and configure an integrated development environment (IDE) 
from which you develop applications and experiment with the solutions provided in this 
book. For security reasons, we don’t recommend installing something unless absolutely 
necessary. With no alternative, it is easier and safer to download a compressed version 
and run the relevant scripts for the respective operating system. You should be able to 
adapt our instructions to install in the future any latest versions and releases of all the 
packages mentioned in the book without any problem. You learn the basics of Java, such 
as creating a class and accepting keyboard input. Documentation is often overlooked, 
but you also quickly learn how to create great documentation for your Java code in this 
chapter.
Note Java 17 Recipes is not intended as a complete tutorial. Rather, it covers key 
concepts of the Java language. If you are truly new to Java, you may want to pick 
up Java 17 for Absolute Beginners by Iuliana Cosmina (Apress, 2022).
