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

When learning how to program in almost any programming language, the first example you will typically test is called "hello world." It is the simplest application possible; the aim is to write the expression "hello world" to whatever user interface the programming environment offers. Executing this program will introduce you to the basics of writing code using the IntelliJ editor, utilizing different types of data to be printed to the user interface and adding comments to your code.

When writing your first program, you will also discover how Java's syntax is constructed and how it relates to other languages such as C or C++. Understanding the syntax is key to starting to read code. You will learn how to distinguish where commands and functions begin and end, how parameters are passed over between blocks of code, and how to leave comments that will help you when revisiting your software in the future.

This chapter covers the basics of writing and testing programs as a first step toward building all the code that you will find in this book.
