What software is JAVA and what is its use?

It is a network-oriented programming language for programmers to create applications, which can be downloaded through the network and run safely on any computing platform. If you add the World Wide Web and the company intranet system, you will have a standard network computing environment. As a distributed and object-oriented programming language, Java allows any computer located anywhere to apply programs on the network.

If you look at Java from a business perspective, Java is a fashionable word. Compared with many other programming languages with a history of 20 years, Java has absorbed various latest achievements in the field of computer science. On the other hand, because Java is still young, it lacks the support of rich programming tools such as Visual Basic or C++.

Like C++, Java is an object-oriented language, which means that software can be compiled in the form of components, and software components can cooperate with each other to meet a certain task. Running Java doesn't have to be done in a network environment. Like other traditional programming languages such as COBOL or Basic, Java can create independent applications. Only Java is better at developing applications on the Internet.

Java is suitable for the development and application of Internet. One reason is that it uses a virtual machine. Virtual machine is a software package used to interpret Java instructions, which allows Java to run on any machine, such as a virtual machine package running under Mac or UNIX. Virtual machine is not the Java language itself, it is interpreter software written for a specific machine. Java's virtual machine strategy is equivalent to Esperanto, which is an artificial international language, making translation and communication between different languages easier.

To call it a universal computer language, Java is the most suitable, that is to say, it can run on all computers (although Java virtual machine software needs to be written for various machines), it can provide soft parts as needed, and it has inherent security mechanisms.

The operating system written in Java, called JavaOS, is a language-based operating system, which seems to have no chance to occupy the PC market. But it provides clues for the future development of Microsoft Windows and MacOS. It may be applied to various instruments and equipment in the future, including TV remote controller and temperature controller.

Web-based content providers are interested in Java technology because it adds interactivity and animation functions, which are the key factors to attract audiences. For software vendors, Java hopes that people can rent software, such as word processors or spreadsheet software, without buying software, which has changed the current business model.

Java also makes the network computer a reality, a $500 personal computer without a hard disk.

Replace the computer with Wintel structure. All this shows the importance of Java, and its supporters regard it as the last and best hope against Microsoft and Gates, which is why some people show fanaticism about Java.
