Java 9: Building Robust Modular Applications

By: Dr. Edward Lavieri, Peter Verhas, Jason Lee

Overview of this book

Java 9 and its new features add to the richness of the language; Java is one of the languages most used by developers to build robust software applications. Java 9 comes with a special emphasis on modularity with its integration with Jigsaw. This course is your one-stop guide to mastering the language. You'll be provided with an overview and explanation of the new features introduced in Java 9 and the importance of the new APIs and enhancements. Some new features of Java 9 are ground-breaking; if you are an experienced programmer, you will be able to make your enterprise applications leaner by learning these new features. You'll be provided with practical guidance in applying your newly acquired knowledge of Java 9 and further information on future developments of the Java platform. This course will improve your productivity, making your applications faster. Next, you'll go on to implement everything you've learned by building 10 cool projects. You will learn to build an email filter that separates spam messages from all your inboxes, a social media aggregator app that will help you efficiently track various feeds, and a microservice for a client/server note application, to name just a few. By the end of this course, you will be well acquainted with Java 9 features and able to build your own applications and projects. This Learning Path contains the best content from the following two recently published Packt products: • Mastering Java 9 • Java 9 Programming Blueprints

Benchmarking options


In the previous section, you learned how to run a benchmark test. In this section, we will look at the following configurable options for running our benchmarks:

  • Modes
  • Time units

Modes

The output of our benchmark results, from the previous section, included a Mode column that had the value of thrpt which is short for throughput. This is the default mode and there are an additional four modes. All JMH benchmark modes are listed and described as follows:

Mode

Description

All

Measures all other modes inclusively.

Average

This mode measures the average time for a single benchmark to run.

Sample Time

This mode measures the benchmark execution time and includes min and max times.

Single Shot Time

With this mode, there is no JVM warm up and the test is to determine how long a single benchmark method takes to run.

Throughput

This is the default mode and measures the number of operations per second the benchmark could be run.

 

To dictate which benchmark mode to use, you will modify your @Benchmark...
