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.

Summary

In this chapter, we provided an overview of the functionality of the most popular packages of JCL: java.lang, java.util, java.time, java.io, java.nio, java.sql, javax.sql, java.net, java.lang.math, java.math, java.awt, javax.swing, and javafx.

The most popular external libraries were represented by the org.junit, org.mockito, org.apache.log4j, org.slf4j, and org.apache.commons packages. It helps you to avoid writing custom code in the cases when such functionality already exists and can just be imported and used out of the box.

In the next chapter, we will talk about Java threads and demonstrate their usage. We will also explain the difference between parallel and concurrent processing. We will demonstrate how to create a thread and how to execute, monitor, and stop it. It will be very useful material not only for those who are going to write code for multi-threaded processing...
