Learning Network Programming with Java

Overview of this book

Network-aware applications are becoming more prevalent and play an ever-increasing role in the world today. Connecting and using an Internet-based service is a frequent requirement for many applications. Java provides numerous classes that have evolved over the years to meet evolving network needs. These range from low-level socket and IP-based approaches to those encapsulated in software services. This book explores how Java supports networks, starting with the basics and then advancing to more complex topics. An overview of each relevant network technology is presented followed by detailed examples of how to use Java to support these technologies. We start with the basics of networking and then explore how Java supports the development of client/server and peer-to-peer applications. The NIO packages are examined as well as multitasking and how network applications can address practical issues such as security. A discussion on networking concepts will put many network issues into perspective and let you focus on the appropriate technology for the problem at hand. The examples used will provide a good starting point to develop similar capabilities for many of your network needs

About the Reviewer

Daniel MÜHLBACHLER got interested in computer science shortly after entering high school, where he later developed web applications as part of a scholarship system for outstanding pupils.

He has a profound knowledge of web development (PHP, HTML, CSS/LESS, and AngularJS), and has worked with a variety of other programming languages and systems, such as Java/Groovy, Grails, Objective-C and Swift, Matlab, C (with Cilk), Node.js, and Linux servers.

Furthermore, he works with some database management systems based on SQL, and also some NoSQL systems, such as MongoDB, and SOLR. This is also reflected in several projects that he is currently involved in at Catalysts GmbH.

After studying abroad as an exchange student in the United Kingdom, he completed his bachelor's degree at Johannes Kepler University in Linz, Austria, with a thesis on aerosol satellite data processing for mobile visualization. This is where he also became familiar with processing large amounts of data.

Daniel enjoys solving challenging problems and is always keen on working with new technologies, especially related to the fields of big data, functional programming, optimization, and NoSQL databases.

More detailed information about his experience, as well as his contact details, can be found at www.muehlbachler.org and www.linkedin.com/in/danielmuehlbachler.
