Java: The Complete Reference, 11th Edition

Java is one of the world’s most important and widely used computer languages. Furthermore, it has held that distinction for many years. Unlike some other computer languages whose influence has waned with the passage of time, Java’s has grown stronger. Java leapt to the forefront of Internet programming with its first release. Each subsequent version has solidified that position. Today, it is still the first and best choice for developing web-based applications. It is also a powerful, general-purpose programming language suitable for a wide variety of purposes. Simply put: much of the modern world runs on Java code. Java really is that important. A key reason for Java’s success is its agility. Since its original 1.0 release, Java has continually adapted to changes in the programming environment and to changes in the way that programmers program. Most importantly, it has not just followed the trends, it has helped create them. Java’s ability to accommodate the fast rate of change in the computing world is a crucial part of why it has been and continues to be so successful. Since this book was first published in 1996, it has gone through several editions, each reflecting the ongoing evolution of Java. This is the eleventh edition, and it has been updated for Java SE 11 (JDK 11). As a result, this edition of the book contains a substantial amount of new material, updates, and changes. Of special interest are the discussions of two key features that have been added to Java since the previous edition of this book. The first is local variable type inference because it streamlines some types of local variable declarations. To support local variable type inference, the context-sensitive, reserved type name var has been added to the language. The second key new Java feature is the reworking of the version number to reflect what is expected to be a faster release cycle, which started with JDK 10. As explained in Chapter 1, Java feature releases are now anticipated to take place every six months. This is important because it is now possible for new features to be added to Java at a more rapid pace than in the past. Although introduced in the previous edition of this book, there are two recently added Java features that are still having a strong impact on Java programmers. The first is modules, which enable you to specify the relationships and dependencies of the code that comprises an application. The addition of modules by JDK 9 represents one of the most profound changes ever made to the Java language. For example, it resulted in the addition of 10 context-sensitive keywords. Modules also significantly impacted the Java API library because its packages are now organized into modules. Furthermore, to support modules, new tools have been added, existing tools have been updated, and a new file format has been defined. Because of their importance, the entirety of Chapter 16 is devoted to modules. The second recently added feature is JShell. JShell is a tool that offers an interactive environment in which it is easy to experiment with code snippets without having to write an entire program. Both beginners and experienced professionals will find it quite useful. An introduction to JShell is found in Appendix B.
