What is Java?

Briefly, the Java environment can be used to develop applications that can run on any computing platform. It is actually a very basic and compact technology, and its overall impact on WorldWideWeb and the business has been comparable to the impact of the PC with the spreadsheet.

Java is a huge promotion force

Java has used dynamic interactive applications to make Web lifelike. It makes developers have a huge power to run TM at once. Moreover, with its JavaAPI and its programming languages, it has generated a new mode of distribution information. This mode is called Java business calculations. It is helping all companies to achieve competitive advantage in a variety of different methods. Net management and control have been greatly simplified. Software allocation is basically free, and it can be achieved immediately. Electronic trade is obtained. Posage cost is reduced. Information and application software Acquired.

On the basis of simple premise, Java is based on all microprocessors. All microprocessors should be in the same language - all internal use chips should be able to work together, seamless and convenient to share information. It has changed the way companies and individuals with the INTERNET. It is now a significant impact on consumer products, and more profoundly affects enterprise calculations.

With Java, you can use your own hardware and software freely. This is because Java is independent of the platform. It also enables you to transcend enterprise computing, allowing the application to operate on a laptop, information kiosk, television, cellular phone, and other large devices.

Companies around the world have found the use of Java countless. All uses can benefit from their unparalleled capabilities, that is, improved reliability, security, and simplifying various different computational products and environments, and saving time and fees are very considerable.

Java is everywhere. It has millions of users, and its development speed is faster than any other computer product before it. It can be located anywhere and can run everywhere. Java is quickly being used to use the facts of communication information, because it can be given to the enterprise, but also bring the end users to seem to be unclear.

Therefore, please take care of Java carefully. Its advantages are easy to find.

"Java is entering business, family and school. It is a technique that is common like Internet itself."

- Oracle Chairman and CEO Larru Ellison

"Java is changing us using the Internet, changing the way we access information in the company, even changing the way we use cellular phones. It is fundamentally changing the method of making information, sales information, and allocation information."

--EarthWeb Chairman and CEO Jack Hidary

Java's coming dragon

A group of engineers at Sun gathered together to think about the digital systems in daily life - because the toaster, thermostat, game consoles and other countless devices contain increasingly complex CPUs - and how they make these numbers System sharing information.

Create a future calculation

Of course, people who make products are all considered to consider their design, depending on the hardware platform, operating system, and application software they use. However, if you want to work together in some of these products, what should I do? What is safety, reliability and network problems?

Therefore, SUN's engineers fold all kinds of products, and then re-assemble them, and its goal is to make these different devices talk to each other. They pass these research objects to each other and understand all other research objects to make them better work together. This reduces the manufacturer's problem to the lowest level and makes consumers easily integrate. When traditional language proves is not applicable, engineers are planning to find some simple modern new language. Thus, Java came into being.

People quickly found that Java may surpass the imagination of engineers. The charm of Java is that it provides developers and users simple. Developers have a wide range of user foundations, platform independence, reduced development costs and consistent implementation environments, while users can benefit from vivid content, instant software, and increased security.

However, Java is really taking off from the WorldwideWeb. Java makes the world vibrate because it makes the web page vivid, and it is very clear soon, Java has much much great potential. People adopt Java because it has unique ability to prepare and deploy applications that can run on any network, any operating system. The time and expense of allocation software are actually no longer existed, making companies can use more resources to develop their products. Moreover, some industrial experts believe that Java may change the software sales model, and change from a fixed price to charge according to the usage, which is more advantageous and can prevent illegal piracy. Java is a general open standard platform for network computing. This platform can be extended from the phone to an extremely important application, based on your existing hardware and software architecture, thereby creating a full networking company or manufacturing exceeding innovation products.

"Because Java has scientificability, we can apply Java to small applications or large applications, putting it chipset and large computers and servers, and serve it for a variety of different application areas."

- Steve Hester, Vice President of Mitsubishi System Marketing

"With Java, you can dynamically distribute and assign interactive business applications that can run the application, when you need to run your application, using a place where you need to run your application."

--Novell's Vice President and General Manager of Company Development Manager Gary Mueller

Java is taking down

In a sense, Java embodies the target of Sun Microsystiems from its 14 years ago. At that time, it created the number of "network is a computer". It is a perfect platform for web-based new network computing model, because it is based on the existing hardware and software architectural structures of all organizations, and can build a whole network.

Java is a complete and comprehensive solution

Java is far more than a programming language, which is the complete computing environment inside and outside the company, and all the best, from the development tool, operating system, server software and thin / fertilizer clients to network management tools, support, training, consulting and integration. Service, all. Java uses very simple, partly because Sun provides a comprehensive unified solution.

The main components include:

* Java development tools and services: helps to simplify products and services to develop Java applications

* Javaos: A compact operating system that allows Java applications to run on network computers and cellular phones.

* Java Virtual Machines: Layer 1 software, embedding computer operating system such as Windows, Macintosh, and UNIX, or running on these operating systems, allowing computers to run Java application software

* Java API: Standard Software Interface, between Java Application Software and Database Retrieval and Security Service Software

* Java chip: a series of microprocessors optimized for Java

* Solstice Workshop: Network Management Tools, Java, Launched

* Java training: a complete course of teacher guidance and multimedia, how to develop Java applications, including a certification program for verifying proficiency

* Javaworkshop support: 900 telephone services, can immediately provide on-demand support for JavaworkShop users (US users only) to support these products on demand, depending on the basis provided by Sun's core technology and services, including:

* Solaris operating system

* Sikstuce Enterprise Management System

* Workshop Developer Tools

* SunSpectrum Support Service

* Internet Consulting and Integrated Services

* Java and Internet education services

* ULTRA workstation and Ultra Enterprise server; Netra server

No wonder big companies and the growing global 2000 companies are using Java computing to do system and its main aspects of their final products. "You don't lock yourself in any company's proprietary technology. Opening means choosing. And Java has room for you to choose."

- Oracle Chairman and CEO LARRY Ellison
