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.

Converting CSV to JSON

Comma Separated Values (CSVs) is an ideal method for storing data in a tabular form. CSV files can be easily moved in and out of several data-processing software tools, such as Microsoft Excel. It is simple and perfect for a quick transfer in a number of environments.

However, JSON is present all around the web, and there is often a requirement to convert the CSV data to JSON in order to use it in a different programming and data-processing environment. Any JSON conversion can occur by using two modes of standard or minimal conversion.

A simple table can be read using table annotations that point to individual values. This is an easy-to-read model where column titles and cell values can be directly referred using Unicode character sets. Normalization may also apply when converting string values to JSON data, which can then be parsed in real time.

The minimal...
