The Early Days of Java

Java essentials

• Object Oriented• Robust• Multi-Threaded• Network savvy• Interpreted and Portable (WORA)• Architecture neutral (wherever it runs, it runs the same)

6

2007 – Java’s heyday

7

2007 Heyday of Java

• JavaOne biggest developer event in the world• Java both Hot and Cool!• Java headed for dominance on any device

– Mobile options open

• FX revolution started (=> TV, Blu-Ray, designers)• Gaming and Virtual Worlds (Wonderland)• Java to become open source (OpenJDK)• JAVA was the Nasdaq Stock Symbol for Sun

The sky seemed the limit

Dark clouds were gathering

took forever…

Smartphone and Tablet revolution – closed platforms

Android (Dalvik VM) left

Java fold

New Kids on the Block - scripting languages,

anything new/hot

What happened in recent years?

• JVMs• JVM languages• JVM platforms (WOR-oqafp)• FX • Java Community

– Vendors– The rest of us– Kids

16

Many JVMs

• Zing• Zulu• BEA JRockit• Sun HotSpot• Apache Harmony• IBM J9 VM• Kaffe• Jikes RVM• JamVM• Excelsior JET• IcedTea• OpenJDK

17

Oracle’s Converged JVM roadmap

• Merge Sun HotSpot & BEA JRockit => Oracle HotSpot JVM– Use HotSpot as the basis for the future JVM

– Cherry-pick features and port– Same JVM for everything from embedded all the way up to

enterprise

• Make JRockit tooling available with unified HotSpot JVM– Mission Control & Flight Recorder (7u40)

18

JVMs on [m]any platform[s]

19

Oracle’s platform roadmap

• Target platforms are– Desktop Client– Enterprise Server– Mobile (feature phones) and Embedded devices

• No [plans for] JVM on iOS or other tablets or smart phones– However: Embedded JVM in iOS and Android Apps

• No Java Applet browser plugin– [please] No more Applets!

Use cases for Compact Profiles

• Kiosk• Hand held device• Home Gateway• Electronic Tollbooth• Oracle Mobile Application Framework

– Generic app for iOS & Android with embedded JVM fordeploying custom Java/Apache Cordova apps

• App Store deployment of Java Client applications– Windows 8, Apple OSX

Java SE 8

• Description- CLDC 8 is an long-anticipated, evolutionary update for CLDC 1.1.1 to bring

the VM, Java language and core API libraries in alignment with Java SE 8

• Key Features- Synchronize Java SE 8 language features into Java ME

- CLDC 8 is an extended strict subset of Java SE 8

- Introduce developer-friendly Java SE APIs

- Includes updated Generic Connection Framework (GCF) 8

- Virtual Machine update to align with Java SE developer tools

- Remain small and enable footprint optimizations

- Backward binary compatible

- Enable 9+ Million Java developers to develop for Java Embedded

CLDC 8 High-Level Overview

CLDC 8

Bringing The World of Java SE to Java ME

28

Many “JVM” languages

JavaClojure

Groovy

JavaScript

ScalaJRuby

Jython

29

Languages that can run on the JVM

30

Java 8 ‘theme’:Interoperability on JVM or The Polyglot JVM

• Easier interoperability between Java and other JVM languages• Project Nashorn: very fast JavaScript engine embedded in JVM

– Available from Java code to execute JavaScript– Allows JavaScript to invoke Java as well– “Oracle is in the process of developing node.jar, a java implementation of node.js to

also run on the JVM via Nashorn”

31

Story of FX

• Started as F3 by Chris Oliver• Announced at JavaOne 2007

– And every JavaOne since

• Java FX Script 1.0 December 2008• 2.0 release October 2011

– (no more FX Script)

• FX 8 – March 2014– Included in OpenJDK– To replace Swing– On desktop & embedded

The Launch of Java 8SE, FX, ME, JDK & JVM

38

Java 8

• Java 8 - Statements/directions/themes– Converged JVM– JavaFX merged into JDK (deprecate Swing)– Abandon Java Applets– Java Client: desktop, embedded (ARM devices); touch screen support (Windows 8)– Bring SE [Embedded] and ME closer together (CLDC 8 and profiles)– Interoperability between JVM languages (Nashorn)

• Language Innovation– Lambda (“closures”) ,– Collections with Streams API– Concurrency– …

Beyond Java 8

• Installer/Embedded JVM• Further language evolution• JigSaw (Modularity)• Java on GPU (Graphics Processing Units) • Cloud• Interoperability• No backward compatibility

beyond three versions for source & target (7,8,9 – no more Java 5,6)– Note: Java 8 does not accept

Java 1.4 as a target
