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.

    1. Select all the correct statements:
      1. JMH is useless since it runs methods outside the production context.
      2. JMH is able to work around some of the 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.
    1. Name two steps necessary to start using JMH.
    2. Name four ways JMH can be run.
    3. Name two modes (performance characteristics) that can be used (measured) with JMH.
    4. Name two of time units that can be used to present JMH test results.
    5. How can the data (results, state) be shared between JMH benchmarks?
    6. How do you tell JMH to run the benchmark for the parameter with the enumerated list of values?
    1. How can the compilation of a method be forced or turned off?
    2. How can the JVM's constant folding optimization be turned off?
    3. How can Java command...
