You´ll see clear code descriptions and layout so that you can get your code running as soon as possible. After reading this book, you´ll come away with the basics to get started writing programs in Java.

Author Iuliana Cosmina focuses on practical knowledge and getting up to speed quickly-all the bits and pieces a novice needs to get started programming in Java. First, you´ll discover how Java is executed, what type of language it is, and what it is good for. With the theory out of the way, you´ll install Java, choose an editor such as IntelliJ IDEA, and write your first simple Java program. Along the way you´ll compile and execute this program so it can run on any platform that supports Java. As part of this tutorial you´ll see how to write high-quality code by following conventions and respecting well-known programming principles, making your projects more professional and efficient.

Finally, alongside the core features of Java, you´ll learn skills in some of the newest and most exciting features of the language: Generics, Lambda expressions, modular organization, local-variable type inference, and local variable syntax for Lambda expressions.

Java for Absolute Beginners gives you all you need to start your Java 9+ programming journey. No experience necessary.
