Java Programming for Beginners

By: SkillSprints Inc., Mark Lassoff

Overview of this book

Java is an object-oriented programming language, and is one of the most widely accepted languages because of its design and programming features, particularly in its promise that you can write a program once and run it anywhere. Java Programming for Beginners is an excellent introduction to the world of Java programming, taking you through the basics of Java syntax and the complexities of object-oriented programming. You'll gain a full understanding of Java SE programming and will be able to write Java programs with graphical user interfaces that run on PC, Mac, or Linux machines. This book is full of informative and entertaining content, challenging exercises, and dozens of code examples you can run and learn from. By reading this book, you’ll move from understanding the data types in Java, through loops and conditionals, and on to functions, classes, and file handling. The book finishes with a look at GUI development and training on how to work with XML. The book takes an efficient route through the Java landscape, covering all of the core topics that a Java developer needs. Whether you’re an absolute beginner to programming, or a seasoned programmer approaching an object-oriented language for the first time, Java Programming for Beginners delivers the focused training you need to become a Java developer.

Working with arrays

In this section we're going to learn about Java arrays. Arrays are Java's most basic and commonly used data structure. Data structures are tools that allow us to store and access sequences of information rather than using individual variables. Variables are great when we have one specific piece of information that we need in our local programming space, but data structures are used when we want to store large or complicated sets or series of information. We're going to start this section with some visual learning modes, and then we'll jump into our NetBeans IDE to write some actual Java code and make use of arrays.
