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.

Java idioms, their implementation, and their usage

In addition to serving the means of communication among professionals, programming idioms are also proven programming solutions and common practices that are not directly derived from the language specification, but born out of the programming experience. In this section, we are going to discuss the ones that are used most often. You can find and study the full list of idioms in the official Java documentation (https://docs.oracle.com/javase/tutorial).

The equals() and hashCode() methods

The default implementation of the equals() and hashCode() methods in the java.lang.Object class looks as follows:

public boolean equals(Object obj) {
return (this == obj);
}
