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.

    1. JMH is useless since it runs methods outside the production context.
    2. JMH is able to work around some JVM optimizations.
    3. JMH allows for measuring not only average performance time but other performance characteristics too.
    4. JMH can be used to measure the performance of small applications too.
  2. Name two steps necessary to start using JMH.
  3. Name four ways JMH can be run.
  4. Name two modes (performance characteristics) that can be used (measured) with JMH.
  5. Name two of the time units that can be used to present JMH test results.
