Overview of this book

Java is one of the most preferred languages among developers. It is 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’ll then focus on understanding object-oriented programming (OOP), with exclusive insights into concepts such as 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 with the help of sample programs and practice examples. You’ll 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 and also build a sample project to help you understand the applications of these concepts. By the end of this Java book, you’ll not only have become well-versed with Java 17 but also gained a perspective into the future of this language and have the skills to code efficiently with best practices.

Summary

This chapter introduced you to the concepts of OOP and how they are implemented in Java. It provided an explanation of each concept and demonstrated how to use it in specific code examples. The Java language constructs of class and interface were discussed in detail. You also learned what overloading, overriding, and hiding are and how to use the final keyword to protect methods from being overridden.

In the Polymorphism in action section, you learned about the powerful Java feature of polymorphism. This section brought all the presented material together and showed how polymorphism stays at the center of OOP.

In the next chapter, you will become familiar with the Java language syntax, including packages, importing, access modifiers, reserved and restricted keywords, and some aspects of Java reference types. You will also learn how to use the this and super keywords, what widening and narrowing conversions of primitive types are, boxing and unboxing, primitive and reference...
