What software is JAVA? What is it mainly used for?

Java is not software, it is just a programming language, and software is written in a programming language, which means that Java can write software.

What does java mainly do?

1. You can write system software, such as the most common office system and various educational administration systems of the school, all of which can be written in java.

2. Writing games, such as the famous game My World, is written in java.

3. Do all kinds of apps and websites backstage, such as Taobao backstage.

4. Wait.

Java is a high-level language used for programming. Similar to our C language and programming language, it is mainly used to make software or design systems.

Java is a computer programming language. Programmers use it to communicate with computers and express their needs and ideas in Java. This process is what we call programming with Java, so we say that Java is a computer programming language. In order to make the computer understand, Java will have a series of rules and conventions. These are the syntax of Java.

And Java's position in programming language is equivalent to English in human language. It can be said that if you master Java, you are not afraid to travel all over the world. Java in the list of TIOBE languages (list of TiOBE languages: list of development languages, based on the statistics of the popularity of current programming languages by senior software engineers and third-party suppliers around the world. ) topped the list all the year round, and it is a well-deserved king of programming languages.

After more than 20 years of development, Java has formed a perfect community ecology, which is mostly used for enterprise-level project development with B/S structure. At present, domestic first-line companies are using Java for project construction. So what can Java be mainly used for?

1.Java can be a website.

Java can be used to write websites. Nowadays, many large websites are written in Jsp, the full name of which is JavaServerPages. It is a dynamic web technology, such as the familiar 163. Some government websites are written in JSP.

2.Java can play games.

When Nokia was still popular, more than 90% of mobile games were developed by Java. There are also games developed by Java on the computer, the most classic of which is My World, and League of Legends, one of the most popular and influential online games in the world today.

3.Java can make software.

General programming languages can be used as software, and Java is no exception, such as Eclipse, MyEclipse and other well-known Java development tools. About developing software components, you can learn JavaSwing programming or awt. For example, enterprise-level application development is dominated by Java, which occupies an extremely important position from the national networking system to the application solutions of small and medium-sized enterprises. There is also the mobile field, and the typical application is mobile games (mainly in China). This is the world of J2ME, but it has a wide range of applications.

4.Java can do Android.

Android is a free and open source operating system based on Linux, and the source code is Java. So the mobile phone systems seen in the market, such as MIUI, Alibaba Cloud, Le Frog and so on. , are redistributed by modifying the source code. Java does Android not only refer to the system, but also the APP. For more developers, they spend more time developing applications.

At present, the employment of Java is very wide, and the recruitment volume of Java development of major recruitment websites is also the largest. In addition to the positions corresponding to Java itself, enterprises also like front-end development, mobile development, testing, products and so on with Java background. It can be said that with Java skills around, it will be easier for you to transfer to various positions and your career planning will be broader.

I hope the above answers are helpful to you!

Java is a high-level language used for programming. It not only absorbs the advantages of C++ language, but also abandons the concepts of multiple inheritance and pointers that are difficult to understand in C++, so Java language has two characteristics: powerful function and simple use. As the representative of static object-oriented programming language, Java language perfectly realizes the object-oriented theory and allows programmers to carry out complex programming in an elegant way of thinking. Java has the characteristics of simplicity, object-oriented, distributed, robustness, security, platform independence and portability, multithreading and dynamics. Java can write desktop applications, Web applications, distributed systems and embedded system applications.

Related work purposes:

1, Java can develop websites, such as portals of some enterprises;

2.Java can do software, for example, information management system, employee punching system;

3.Java is used for mobile phone development, such as making a mobile phone system.

4.Java plays games, such as some online games, mobile games and so on.

The future development direction of Java development engineers can be roughly divided into two categories:

First, become a manager, such as product development manager, technical manager, project manager, etc.

The second is to continue his technical work and become a senior software engineer and requirements engineer.

Java language (a computer language, especially for creating websites)

At first, people tried to reduce cross-system repetitive coding.

That is to say, the initial idea of being lazy is to do it on some small electronic devices.

Later, people found that it was excellent in cross-platform (running on different operating systems) and portability on computers.

The popularity of the Internet shows its superiority (especially suitable for multi-person cooperation).

Then it extends many aspects of technology.

Such as big games.

Complete software design, development, testing and bug modification, including business requirements communication, detailed design of functional modules, business function realization and unit testing, and system maintenance; Participate in product concept and architecture design; Write relevant technical documents; Support pre-sales technical services; Support the application service of the project to the product.

Java is the general name of Java programming language (hereinafter referred to as Java language) and Java platform introduced by SunMicrosystems in May 1995. HotJava browser implemented in Java (supporting Javaapplet) shows the charm of Java: cross-platform. Java platform consists of Java virtual machine and Java application programming interface (API). Java is divided into three systems: J2SE(Java2StandardEdition), J2EE (Java 2 Platform, Enterprise Edition) and J2ME(Java2MicroEdition). 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 VisualBasic 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 network computers a reality. A $500 PC without a hard disk will replace the Wintel computer. 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.
