Thus rather than using contrived examples of OO concepts, instructors can use some of Java’s basic features the class library, Swing and GUI components to motivate these discussions in a natural way. It explains how the code is organized in packages, defines all the main types, and the list of reserved and restricted keywords. For example, it’s almost impossible to discuss GUI-based Java ap-plications without discussing inheritance and polymorphism.
The book proceeds by presenting a more detailed view of Java as a language. With the basics in place, we then explain and discuss Object-Oriented Programming ( OOP) principles, how Java implements them, and how a programmer can take advantage of them to write high-quality code that is easy to maintain. Second, Java makes it easy to translate your programs (screens, menus and messages) to different human languages.

It starts with basic Java-related definitions and the main terms, walks the reader through the installation of the necessary tools and Java itself, and explains how to run (execute) a Java program and the examples of the code provided with this book. If, for example, your Java program needs to print some messages, it asks JVM to do this, and JVM know how to deal with your printer.

As you progress, you’ll move on to advanced topics such as Java libraries, database management, and network programming, which will hone your skills in building professional-grade apps.įurther on, you’ll understand how to create a graphic user interface using JavaFX and learn to build scalable apps by taking advantage of reactive and functional programming.īy the end of this book, you’ll not only be well versed with Java 10, 11, and 12, but also gain a perspective into the future of this language and software development in general. You will also delve into core programming topics that will assist you with error handling, debugging, and testing your apps. Next, you’ll cover fundamental programming structures of Java such as data structures and algorithms that will serve as the building blocks for your apps. You will then focus on understanding object-oriented programming (OOP), with exclusive insights into concepts like abstraction, encapsulation, inheritance, and polymorphism, which will help you when programming for real-world apps.
