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

Business applications have lots of special-case conditions. Such conditions may include finding changes in allocation rules starting at a particular year, or handling different types of employees differently based on their designation. To code for such special cases, you will require conditional logic. You basically tell the computer to perform a set of actions when a particular condition is met.

Before we delve into advanced Java topics, you need to know the basics of Java syntax. While some of this material might seem simple, you'll find you need to use the techniques and syntax shown in this chapter repeatedly in your applications.

As you've seen in Chapter 1, Getting Started, Java's syntax borrows heavily from C and C++. That's true for conditional statements that control the flow of your programs as well. Java, like most computer languages, allows you to do this. This chapter covers the basic syntax of the Java language, especially ways in...
