Learn Java 12 Programming

By: Nick Samoylov

Overview of this book

Java is one of the preferred languages among developers, used in everything right from smartphones, and game consoles to even supercomputers, and its new features simply add to the richness of the language. This book on Java programming begins by helping you learn how to install the Java Development Kit. 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. 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 also delve into core programming topics that will assist you with error handling, debugging, and testing your apps. 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. Further 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. By 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.

In this chapter, you have learned what Java packages are and the role they play in organizing code and class accessibility, including the import statement and access modifiers. You also became familiar with reference types: classes, interfaces, arrays, and enums. The default value of any reference type is null, including the String type.

You should now understand that the reference type is passed into a method by reference and how the equals() method is used and can be overridden. You also had an opportunity to study the full list of reserved and restricted keywords and learned the meaning and usage of the this and super keywords.

The chapter concluded by describing the process and methods of conversion between primitive types, wrapping types, and String literals.

In the next chapter, we will talk about the Java exceptions framework, checked and unchecked (runtime) exceptions...
