Java 9 High Performance

By: Mayur Ramgir, Nick Samoylov

Overview of this book

Finally, a book that focuses on the practicalities rather than theory of Java application performance tuning. This book will be your one-stop guide to optimize the performance of your Java applications. We will begin by understanding the new features and APIs of Java 9. You will then be taught the practicalities of Java application performance tuning, how to make the best use of garbage collector, and find out how to optimize code with microbenchmarking. Moving ahead, you will be introduced to multithreading and learning about concurrent programming with Java 9 to build highly concurrent and efficient applications. You will learn how to fine tune your Java code for best results. You will discover techniques on how to benchmark performance and reduce various bottlenecks in your applications. We'll also cover best practices of Java programming that will help you improve the quality of your codebase. By the end of the book, you will be armed with the knowledge to build and deploy efficient, scalable, and concurrent applications in Java.

Importance of error handling

Error handling refers to the systematic approach of monitoring, identifying, and fixing errors in application and programming. Despite the ease of the Java programming language, application and programming errors are unavoidable. This is because each application or program is developed, modified, and updated by hundreds of users, and inconsistencies of logic and the use of that application or program gives rise to multiple errors and problems.

This can cause the program or application to crash and increases the risk of losing all customers. Through the use of error handling, programmers can prevent or fix errors in an application. If this is not possible, then the application is terminated as a last resort. Error handling helps programmers meet the following objectives:

  • Helps in the identification and anticipation of an application or programming...
