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.

JMH benchmark parameters

There are many benchmark parameters that allow for fine-tuning the measurements for the particular needs of the task at hand. We are going to present only the major ones.

Mode

The first set of parameters defines the performance aspect (mode) the particular benchmark has to measure:

  • Mode.AverageTime: Measures the average execution time
  • Mode.Throughput: Measures the throughput by calling the benchmark method in an iteration
  • Mode.SampleTime: Samples the execution time, instead of averaging it; allows us to infer the distributions, percentiles, and so on
  • Mode.SingleShotTime: Measures the single method invocation time; allows for the testing of a cold startup without calling the benchmark method continuously...
