Transitioning to Java

Transitioning to Java

4.8 (6)
By: Ken Fogel

Overview of this book

This comprehensive guide will help non-Java developers already using different languages transition from their current language to all things Java. The chapters are designed in a way that re-enforces a developer’s existing knowledge of object-oriented methodologies as they apply to Java. This book has been divided into four sections, with each section touching upon different aspects that’ll enable your effective transition. The first section helps you get to grips with the Java development environment and the Maven build tool for modern Java applications. In the second section, you’ll learn about Java language fundamentals, along with exploring object-oriented programming (OOP) methodologies and functional programming and discovering how to implement software design patterns in Java. The third section shows you how to code in Java on different platforms and helps you get familiar with the challenges faced on these platforms. In the fourth section, you’ll find out how you can manage and package your Java code. By the end of this Java programming book, you’ll have learned the core concepts of Java that’ll help you successfully transition from a different language to Java.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “We begin with a class that implements Runnable. actionCounter is the number we will count down from in the thread.”

A block of code is set as follows:

private final double principal = 100.0;
private final double annualInterestRate = 0.05;
private final double compoundPerTimeUnit = 12.0;
private final double time = 5.0;

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

private final NumberFormat currencyFormat;
private final NumberFormat percentFormat;

Any command-line input or output is written as follows:

brew install openjdk@17

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “When you click on Accept, the code from the JShell editor will be transferred to JShell.”
