Java Data Analysis

By: John R. Hubbard

Overview of this book

Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the aim of discovering useful information. Java is one of the most popular languages to perform your data analysis tasks. This book will help you learn the tools and techniques in Java to conduct data analysis without any hassle. After getting a quick overview of what data science is and the steps involved in the process, you’ll learn the statistical data analysis techniques and implement them using the popular Java APIs and libraries. Through practical examples, you will also learn the machine learning concepts such as classification and regression. In the process, you’ll familiarize yourself with tools such as Rapidminer and WEKA and see how these Java-based tools can be used effectively for analysis. You will also learn how to analyze text and other types of multimedia. Learn to work with relational, NoSQL, and time-series data. This book will also show you how you can utilize different Java-based libraries to create insightful and easy to understand plots and graphs. By the end of this book, you will have a solid understanding of the various data analysis techniques, and how to implement them using Java.

Why Java?


Java is, as it has been for over a decade, the most popular programming language in the world. And its popularity is growing. There are several good reasons for this:

  • Java runs the same way on all computers

  • It supports the object-oriented programming (OOP) paradigm

  • It interfaces easily with other languages, including the database query language SQL

  • Its Javadoc documentation is easy to access and use

  • Most open-source software is written in Java, including that which is used for data analysis

Python may be easier to learn, R may be simpler to run, JavaScript may be easier for developing websites, and C/C++ may be faster, but for general purpose programming, Java can't be beat.

Java was developed in 1995 by a team led by James Gosling at Sun Microsystems. In 2010, the Oracle Corporation bought Sun for $7.4 B and has supported Java since then. The current version is Java 8, released in 2014. But by the time you buy this book, Java 9 should be available; it is scheduled to be released in late 2017.

As the title of this book suggests, we will be using Java in all our examples.
