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

In this chapter, you learned how a Java application can be executed using an IDE or the command line. Now, you can write applications and launch them in a manner that’s appropriate for the given environment. Knowledge about the JVM structure and its processes – classloading, linking, initialization, execution, GC, and application termination – provided you with better control over the application’s execution and transparency regarding the performance and current state of the JVM.

In the next chapter, we will discuss and demonstrate how to manage – insert, read, update, and delete – data in a database from a Java application. We will also provide a short introduction to the SQL language and its basic database operations, including how to connect to a database, how to create the database’s structure, how to write database expressions using SQL, and how to execute them.
