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.

I/O streams

Any software system has to receive and produce some kind of data that can be organized as a set of isolated inputs/outputs or as a stream of data. A stream can be limited or endless. A program can read from a stream (then it is called an input stream), or write to a stream (then it is called an output stream). The Java I/O stream is either byte-based or character-based, meaning that its data is interpreted either as raw bytes or as characters.

The package contains classes that support many, but not all, possible data sources. It is built for the most part around the input from and to files, network streams, and internal memory buffers. It does not contain many classes necessary for network communication. They belong to the,, and other packages of Java Networking API. Only after the networking source or destination is established (a network...
