Introduction toIntroduction toJava TechnologyJava Technology



Java History

● The Java platform was created by James Goslingas a "side effect" in the "Green project" started at

Sun in 1991● Original idea was to be able to control a variety of

devices with different hardware and softwareplatforms – toaster

● The advent of the Web and the NetscapeBrowser gave Java a new purpose and market

Why Java for Developers?

• Portability of the application> Write once, run on many different platforms (for example

on Solaris, Linux, Windows, Mac OS...)

• Increased Productivity> Studies have shown 2x productivity compared to C++> Not only during coding phase, but also during testing and

maintenance!

• Tool Support> The industry has spent most of the tools effort in the past

several years on Java tools>

NetBeans, Eclipse, JBuilder, ...



Why Java for End-Users?

• Portability> A Java application does not mandate a particular

hardware / operating system platform

• Many Java-based free software> Virtually in every possible area you can think of

• Java programs are very secure> Have you heard of Java virus?



Why Java for Businesses?

• No vendor lock-in

• They can pick and choose the best of breed Java-based enterprise application platform

> Vendors compete in the area of performance, scalability,tools, and support

• They can pick and choose the best of breed Java-based enterprise applications> A wide variety of choices based on price, vendor

reputation, support, etc

• There are so many production quality Java-basedopen-source software

How Do You Predict the Future?

• Generally accepted “Laws of computing”

• Technology trends

• Adoption cycles of a technology



26

Computing "Laws"

• Moore's Law> Computing speed roughly doubles every 18-24 months

• Gilder's Law> Network bandwidth capacity doubles roughly every 12

months

• Metcalfe's Law

> The value of a network grows exponentially as thenumber of nodes increases> Technology echo-system is being formed



27

Trends in Information Technology

• Proliferation of computing devices

• Mobile devices as major computing platform

• Networking everywhere by everything andeverybody

• Participation (software users & developers)

• Social networking

• Web as a computing platform

• Software as a service

• Open source movement

Relevance of Java Technology

• The portability of Java application (Write Once RunEverywhere) is becoming increasing critical as thenumber of computing devices proliferate>

A single Java application runs over thousands of devices

Mobile Devices Are Becoming

Major Computing Platform!



33


• Before Java technology:> Software development and deployment was painful

(Developers and Network operators)>

New software installation was close to impossible(Users)

• With Java technology:> Most of the mobile devices already have Java platform

pre-installed> Java is the most popular programming language for

writing mobility applications> You can download many Java applications

Open Source Momentum

“the most significant all-encompassing andlong-term trend that the software industryhas seen since the early 1980s.”

IDC Group Report

August 2006

• Some Facts

> 800,000 the number of developers contributing to open source

> 87% estimated number of US businesses using open source

• Increasingly a required in established markets, including government• Critical in developing economies (Brazil, Russia, India, China)



54

Why Should Developers Care

• Great learning tool

• Opens new Opportunities

• Build a reputation/visibility in the community

• Build on your core technologies

• Borrow your non-core technologies

• Potentially lower maintenance burden

• Contribute to and leverage a code commons

• Work in community with the best and brightest



55


• Pretty much all Java based technologies andsolutions are in open-source form> JDK>

Tomcat> NetBeans, Eclipse> GlassFish app server > OpenESB

> OpenSSO> OpenDS> OpenSolaris> Many more
