Transitioning to Java

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.

Java Syntax and Exceptions

In this chapter, we will begin by looking at the syntax of the Java language. It might seem strange that it took till this chapter to look at syntax. To understand why, I must let you in on a secret: you already know how to code. This is the audience this book is for – you can program but have little or no experience with Java. I have no doubt that you could understand what was happening in every code sample you have seen so far. We will now formalize the Java syntax.

Here are the topics we will cover:

  • Understanding coding structures
  • Handling exceptions

By the end of this chapter, you will be able to organize Java code into methods and classes. Decision-making and iteration in Java code are presented. When things go wrong, there can be, in many situations, the need to leave the code that caused the error and either carry out additional processing to solve the problem or exit the program. This is the role of exceptions.
