The Java Platform

More than just a language


Java virtual machine

Java Virtual Machine

  • Layer between business application and OS/Hardware platform

  • Protects developer from differences in OS while…

  • providing access to the platforms services

  • Defines object-oriented, feature-rich, Java language


Fitted as standard

Fitted As Standard

  • Wide variety of APIs for normal and specialized tasks

  • Database, Threading, GUI, Logging, Regex, Zip, I18N, Reflection, Remote Invocation

  • OOP without the academically-inspired paraphanalia of C++

  • Business-Oriented Engineering


More where than came from

More Where Than Came From

  • Public Key Cryptography

  • Authentication and Authorization

  • XML Processing

  • 2-D and 3-D graphics

  • JMX (Remote management of h/w and s/w)

The java platform

J2EE

For successful enterprise applications:

  • Scaleable

  • Secure

  • Component-Based

  • Multi-client (Web, PDA, Desktop)


The java platform

J2ME

To get mobile:

  • Lightweight JVM

  • Same syntax

  • Extra APIs

  • Java becoming standard on mobiles and PDAs

  • Small vendors can compete in hi-tech


And more

And More

  • Web services

  • JINI (intelligent networks)

  • Java cards

  • Other things beginning with J (and ending in ‘let’)


Java and opensource

Java and Opensource

  • Vibrant java development community

  • Meritocracy among products

  • Libraries, IDEs, RAD tools, engineering techniques, test harnesses

  • By engineers, for engineers


Java is good for business because

Java Is Good for Business Because…

  • Wide customer base

  • Platform Independant

  • 4 million developers and counting

  • Enabling tooling = high productivity

  • Vast license-free resources = low costs
