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

Datagram Transport Layer Security


Datagram Transport Layer Security (DTLS), is a communications protocol. The protocol provides a layer of security for datagram-based applications. DTLS permits secure communications and is based on the Transport Layer Security (TLS) protocol. Embedded security helps ensure messages are not forged, tampered with, or eavesdropped.

Let's review the relevant terminology:

  • Communication protocol: A set of rules that govern how information is transmitted.
  • Datagram: A structured transfer unit.
  • Eavesdropping: Undetected listening to in-transit data packets.
  • Forgery: Transmission of a packet with falsified sender.
  • Network packet: A formatted unit of data for transmission.
  • Tampering: The altering of data packets after the sender transmits them and before the intended receiver receives them.
  • TLS protocol: The most common network security protocol. Uses, as an example, IMPA and POP for email.

The DTLS Java Enhancement Proposal 219 is aimed at creating an API for the DTLS versions...
