The Event

The Delhi-NCR JUG excitingly hosted Mr. Nikhil Nanivadekar, to bring to you deep dive sessions in Java.

Java is moving forward faster, and one cannot afford to stay behind. Java 10 was released last month and we are looking at the release of Java 11 in just a few months. Yet, organisations hold back to move their applications to Java 9 just because of the fear of breaking their existing code. The attendees learnt how to make your projects Java 9 compatible with Nikhil.

Nikhil also helped the audience choose the collection classes across JDK, Eclipse, Apache and Guava, a crucial decision for any project.

The session was for all Java programmers, architects or managers.

Session details

•  Session 1: Collections.compare:JDK, Eclipse, Guava, Apache

Collections are a staple in any programming language: the need to collect, sort, or iterate over values is needed by nearly all developers. The Java language introduced the Collections framework long ago. It has plenty to offer, but many find it lacking: the number of collection libraries as active open source projects demonstrates the need for something else. This session does a holistic comparison of the most-common collections (pun intended!) frameworks, what they have to offer, and what you should consider for your next project. It also shows common programmer use cases; how each library handles them; and the impact on memory, processing power, and ease of use/coding. Come and let us help you choose the right bag for your tricks!

• Session 2: How to Make a Project Java 9 Compatible

Java 9 brings numerous changes that might break existing applications. This presentation is a case study of making a third-party Java Collections library (Eclipse Collections) Java 9–compatible. You will get an overview of all the steps taken and the evolution of the final, Java 9–compatible product. These steps are essentially similar to those you might have to take to upgrade your application to use JDK 9. The session covers available tooling and simple yet practical tips and tricks that will help you in the upgrade process.
