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.

Code is written for people

The first decades of programming required writing machine commands so that electronic devices could execute them. Not only was it a tedious and error-prone endeavor, but it also required you to write the instructions in a manner that yielded the best performance possible because the computers were slow and did not do much code optimization, if at all.

Since then, we have made a lot of progress in both hardware and programming. The modern compiler went a long way towards making the submitted code work as fast as possible, even when a programmer did not think about it. We talked about it with specific examples in the previous chapter, Chapter 17, Java Microbenchmark Harness.

It allowed programmers to write more lines of code without thinking much about the optimization. But tradition and many books about programming continued to call for it, and some...
