Minecraft Modding Course at Elementary School - Teach Java to Kids

By Guest Blogger Arun Gupta

Cross posted from weblogs.java.net/blog/arungupta/archive/2015/03/22/minecraft-modding-course-elementary-school-teach-java-kids

Exactly two years ago, I wrote a blog on Introducing Kids to Java Programming using Minecraft. Since then, Devoxx4Kids has delivered numerous Minecraft Modding workshops all around the world. The workshop material is all publicly accessible at bit.ly/d4k-minecraft. In these workshops, we teach attendees, typically 8 - 16 years of age, how to create Minecraft Mods. Given the excitement around Minecraft in this age range, these workshops are typically sold out very quickly.

One of the parents from our workshops in the San Francisco Bay Area asked us to deliver a 8-week course on Minecraft modding at their local public school. As an athlete, I'm always looking for new challenges and break the rhythm. This felt like a good option, and so the game was on!

My son has been playing the game, and modding, for quite some time and helped me create the mods easily. We've also finished authoring our upcoming O'Reilly book on Minecraft Modding using Forge so had a decent idea on what needs to be done for these workshops.

Minecraft Modding Workshop Material

All the workshop material is available at bit.ly/d4k-minecraft.

Getting Started with Minecraft Modding using Forge shows the basic installation steps.

These classes were taught from 7:30am - 7:45am, before start of the school. Given the nature of workshop, the enthusiasm and concentration in the kids was just amazing.

Java in Phantasialand

Java enthusiasts, developers, and architects are gathering next week in Phantasialand, an amusement park close to Cologne, Germany. The conference is a mix of a tradition conference sessions and fun community activities.

In the 20 years of Java keynote, Marcus Lagergren will go down memory lane to reflect on his time on the JVM teams and share his view of the future of Java. Oracle engineers are presented a number of sessions on Java SE 8 and lambdas, Internet of Things and Java EE. Check the schedule.

In the Early Adopters’ area, there will be a hackergarten with 30 minute presentations on development topics, after which interested parties will be able to collaborate on a project.

Java 9 and Beyond

In his keynote at EclipseCon last week, Chief Java Architect Mark Reinhold talked about the main features of Java 9. It will introduce modularity to create a scalable and more secure platform.  The flexibility of modules will allow developers to use just a small part of SE, whether they are constrained by a small device or multiple virtual instances in a cloud environment. 


There are four main JEP (JDK enhancement proposal) for Java 9, which are: 

- JEP 200 defines the modular structure

- JEP 201 modularize the source code

- JEP 220 introduced modular runtime images

- The last JEP will be delivered hand in hand with JSR 376 introducing the actual module system for the Java platform.

There are two projects about features beyond Java 9. Project Valhalla is about value types, generic specialization and Var handles. Project Panama is about a foreign function interface (FFI), data layout control and Arrays 2.0

EclipseCon NA 2015!

Eclipse platform, languages, tools, cloud and Internet of Things will be some of the topics at EclipseCon 2015. The conference is taking place this week in Burlingame California. 


If you attend, don't miss: the Java 9 and Beyond keynote session, the iOS Development with Eclipse and Java - Yes it is possible! conference session and the Eclipse and The Cloud Hosted Development Platform BoF 

Java 9 and Beyond
Mark Reinhold, Architect
Thursday, March 12, 9:00 a.m. – 10:00 a.m.

Java 9 will introduce a standard module system to the platform in order to modularize the platform itself, improve performance and security, and simplify the development and maintenance of large applications. Mark will explain the impact and benefits of Java 9, and then offer a highly-speculative sneak preview of "life after Java 9," the advanced features currently in development for the Java virtual machine and language.

iOS Development with Eclipse and Java - Yes it is possible!
Shay Shmeltzer, Director of Product Management and Strategy, Oracle
Tuesday, March 10, 3:00 p.m. – 3:35 p.m.

In this demo focused session we'll show you how Oracle enables you to develop Java applications that install and run on iOS devices (and Android too). Leveraging Java for business logic, rich set of UI components for HTML5 based UIs, device feature integration and a complete MVC you can create on-device cross platform application with ease. We'll explain the architecture and show you the development experience in Eclipse.

BoF Session: Eclipse and The Cloud Hosted Development Platform                              Wednesday, March 11, 2015 - 19:00 to 20:00, Sandpebble AB

Cloud has emerged as a leading platform for application deployment, but can it act as the platform for application development? How do you integrate Eclipse and Mylyn with cloud hosted ALM solutions? How does Hudson continuous integration work in such an environment?  What features should you be looking for when picking up a cloud platform for your development team? Join us as we discuss and demonstrate the emerging trends in cloud based enterprise application development.

Announcing Java SE 8 Update 40

Improved performance, scalability and administration in Java SE 8 Update 40 will allow Java developers to innovate faster and improve application services. Here are some features and changes including JavaFX updates: 

JVM Reaction to Memory Pressure: “Memory pressure” is a property that represents the total memory usage (RAM) on the system. This new feature can be leveraged to reduce the amount of memory used on a system where multiple JVMs are deployed and control the amount of memory designated to be consumed by each JVM, avoiding Out of Memory Errors (OOMEs) from occurring.

Improvements to the native packager: Enables developers to create native-feel applications that do not require clients to have an existing Java Runtime installed. These self-contained applications can then be deployed into areas like the Mac app store. The application developer has full control over the runtime and application entry points.

Ability to modernize the JavaFX stack on Mac OS X: The JavaFX media stack has been ported on Mac OS X® from QTKit and Quicktime, which have been deprecated, to the newer AVFoundation framework. With this, developers using the JavaFX media stack can now gain Mac App Store acceptance and have the opportunity to have their applications released on the Mac App Store. 

Nashorn Support: Numerous Nashorn optimizations including support for dynamic languages are incorporated into this release. Also added is a Nashorn Class Filter, which provides fine-grained control over access to Java classes from JavaScript code via a new filtering interface. 

New Time Zone Date Updater Tool: This tool can consume the ‘raw’ time zone data (tzdata) rules from the IANA time zone registry database and convert those to the necessary format required by the JRE. This provides users with the ability to immediately update the JDK/JRE time zone rules with the latest updates from IANA.
