Overview of this book

Java is one of the most preferred languages among developers. It is 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’ll then focus on understanding object-oriented programming (OOP), with exclusive insights into concepts such as 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 with the help of sample programs and practice examples. You’ll 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 and also build a sample project to help you understand the applications of these concepts. By the end of this Java book, you’ll not only have become well-versed with Java 17 but also gained a perspective into the future of this language and have the skills to code efficiently with best practices.

A word of caution

The described harness takes away most of the worries of the programmer who measures the performance. And yet, it is virtually impossible to cover all the cases of JVM optimization, profile sharing, and similar aspects of JVM implementation, especially if we take into account that JVM code evolves and differs from one implementation to another. The authors of JMH acknowledge this fact by printing the following warning along with the test results:

The description of the profilers and their usage can be found in the openjdk project (http://hg.openjdk.java.net/code-tools/jmh/file/tip/jmh-samples/src/main/java/org/openjdk/jmh/samples). Among the same samples, you will encounter a description of the code generated by JMH, based on the annotations.

If you would like to get really deep into the details of your code execution and testing, there is no better way to do it than to study the generated code. It describes all...
