Speaking in simple language, Java is a platform for developing and running programs, games and other applications written using it. We will talk about it in more detail, as well as its appearance on your computer, in this article.
Program description
The first version of the Java program was created by the North American developer Sun Microsystems at the end of the previous century. Initially, it was called “Oak”, that is, “oak” and was intended for programming electronic equipment in everyday life.
Programmers and advanced PC users used Java on devices to write codes for so-called "applets." This is the name used in professional environments for applications that can be operated via a browser. For example:
- Calendar;
- Clock widget;
- Guest book
- An online community that allows you to communicate in real time.
But Java is needed on a computer not only for writing programs. It is also needed for their work. Nowadays, many applications, games and Internet sites use Java resources. This means that they require the current version of this program to work.
For example, the popular Minecraft will not start working if Java is not installed. A programming system such as an IDE will not start either. It includes a text editor, debugger and other features that are useful for creating new applications on your computer.
Why is Java already installed on my computer?
Many operating systems, including Windows (starting with Windows 98), already have the Java program integrated, and it appears immediately after installation. It is also possible that during the installation of one or another Java games will be installed with it automatically. This is why it is strictly forbidden to remove Java. This may cause many other applications installed on your PC to fail.
Sometimes the user will receive notifications that an updated version of the Java program is available. These updates will help you avoid problems running other applications in the future.
Often the user sees installed programs on your PC or smartphone and doesn’t know what they are for. The same is true with the Java program. However, many users still wonder what a Java program is for, in order to understand what functions are assigned to it and use them to the maximum.
Java technology
Java is a special programming language in which video games and numerous applications are written. Thanks to Java software, people can play online games, view 3D images, calculate interest on loans, and communicate with people around the world. Applications written in this programming language that can be accessed directly from the browser are called "applets". Many large companies use Java applets for systems ecommerce and intranet applications. On this moment Over 9 million software developers work with the Java platform. It is used in all major industry segments. It is especially widely used in computers and networks. This popularity is due to the efficiency, versatility, portability of platforms and the security of the technology, which makes it best choice for network computing. To understand why Java is needed, just look at your PC or mobile phone. Only through this program can you play various games, since most of them were written on its platform. This program is also used in all Blu-ray players. This technology is used to operate set-top boxes, lottery terminals, printers, web cameras, medical devices, car navigation systems, parking payment machines, etc.
Advantages of the Java Program
The main advantage of Java is that on its platform you can write software that can later be run on almost any other platform. In addition, it allows you to create programs that run in a web browser and have access to web services. As a rule, when asked by the user, is Java needed? You can answer with an example that without this technology it would be impossible to buy anything on the Internet; many surveys are developed on its platform. And about multifunctional and effective applications for mobile phones without this technology would be forgotten. Java has left Apple and Android far behind as it is used in 3 billion cell phones. Now you know everything about the Java program, why this technology is needed, and how it can be successfully used.
