Preface
Developing codes that are correct in a fast manner is a difficult task, even for senior
developers. In conjunction with the abilities of the developer, great tools are involved
in providing a simple, flexible, and fast way of developing software. IntelliJ IDEA is
one of the most powerful IDEs for Java developers, extending facilities you can find
in common IDEs and providing features you’ve probably never seen before.
In this this book, you will learn how to extract the maximum from IntelliJ IDEA
12, beginning with understanding the basic concepts and applying features in real
development challenges. You will see your development speed improve naturally
and understand why IntelliJ IDEA is considered to be the smartest IDE in the world.
What this book covers
Chapter 1, Getting Started with IntelliJ IDEA 12, presents some features in a superficial
way. The intention here, is to show you the features you can expect in IntelliJ IDEA.
The chapter begins by showing common features, then it shows you what is new in
this version of the IDE. You will also see the differences between the Community
Edition and Ultimate versions, and how to install and configure this software. At the
end of the chapter is a section where you will see what you can expect in the future
versions of IntelliJ IDEA.
Chapter 2, Improving Your Development Speed, will provide a wide range of
functionalities that will improve your development speed. In the beginning,
it presents to you the main visual interface of the IDE. After this, it shows you
how to improve your productivity using the features of IntelliJ IDEA such as the
productivity guide, live templates, and navigation usabilities. More development
speed techniques are discussed later in the chapter, such as organizing tasks using
your favorite issue tracker and how to use TODO marks. At the end of the chapter,
a small list of diverse plugins is presented.
