What is JAVA?
Our today's article will be devoted to the topic,which, most likely, is interesting to a narrow circle of people. We will talk about the programming language JAVA. The newest technologies have long been advanced, however, this method of programming is still used by many specialists. Let's look at this language and see what its features are. So:
What is JAVA?
As we noted above, JAVA is a languageprogramming, that is, creating programs that perform various important and secondary functions. It should be noted that JAVA is not only the language itself, but also a platform on which it is possible to create and use applications written in JAVA. Where did this interesting name come from? JAVA is a sort of coffee, which is very fond of programmers. We can also watch the corresponding logo in many JAVA applications.
The purpose of any programming language is reducedto writing programs for the correct and efficient operation of any electronic device. Initially, JAVA was created in order to manage conventional household appliances. However, the creators of the language quickly understood the possible prospects of their work and expanded the scope of their activities.
The scope of JAVA is the following picture:
- Creating desktops and applets. This product is created to order.
- Creation of mobile applications. A separate programming world in the JAVA universe.
- Various server applications, which are mainly focused on working with the network.
Let's talk a little about the peculiarities of the languageJAVA and what is JAVA update. Its main feature is the use of bytecode. After creating the program, it is translated into the bytecode processed by the JAVA machine. A JAVA machine is a program that interprets the bytecode for devices that need to be controlled. From this feature follows the main advantage of the language - its independence. Using universal bytecode allows it to work with any device and with any environment. The catch is in this case only in the existence of the necessary JAVA machine for this equipment, which will interpret the bytecode. A flexible security system is another feature of JAVA programming. The security lies in the fact that the execution of the program is completely under the control of the JAVA-machine. Operations that exceed the program's authority are immediately interrupted. As minuses of the JAVA language, experts sing out the low speed of programs and algorithms. However, the developers do not sit back and try to solve the problem of low productivity. Already, various technologies have been developed that speed up the system as a whole.
A special mention is made of such a language traitJAVA, as versatility. James Gosling - the author of the JAVA language - says that modern programming is shifting towards the development of various network applications. Well, the language JAVA perfectly suits these modern requirements. The universality of language, as Gosling notes, consists in the breadth of its application. You can write programs on JAVA for smart cards, for on-board computers, for network applications of large organizations. And these are only the main areas of work with the help of JAVA.
What is JAVA tm? The most popular lotions created in JAVA language are applets and servlets. Let's see what it is. An applet is a bytecode that functions in a web browser. This program gives more interactive features to the user than the HTML code. A servlet is also a program that runs on the server and significantly expands its functions.
Now I would like to touch a little moreJAVA-machines. As mentioned above, the virtual machine works with a universal bytecode and explains or translates its execution for the hardware. Each equipment needs its own version of the JAVA machine. It is possible to download JAVA-machines for various devices. Enter your request into any search engine and proceed with the download.
As we have already mentioned, JAVA is used forprograms of mobile devices. It means that the JAVA language is the best suited for programming applications on phones. In recent years, touch phones with software from Apple and Microsoft are gaining popularity. JAVA is moving to the distant future, however, the time when this programming language will again take the leading position in the international mobile device markets is not far off.
Well, in conclusion, in order to finallyTo answer the question about what JAVA is, let us touch on such an important area of JAVA programming as the programming of JAVA games. You can watch these games on your mobile phones. The JAVA language is perfect for creating such products.
New technologies are developing at an incredible pace. Recently, humanity could not imagine all the comforts people enjoy today. Our life was greatly facilitated by computer technologies, without which it is already impossible to imagine tomorrow.
