What is the java system

java system

The Java system or language (in English: Java) is one of the computer programming languages, and it is a language that enables programmers to write computer instructions using commands in the English language instead of writing in digital symbols, and Java is a high-level language, because people can read and write it easily, it is like a language English has a set of rules that determine how to write instructions, and after the writing process, the instructions are translated into digital codes that the computer understands and works to implement.

The history of the creation of the java language

The company “Sun Microsystems” created the Java system, where James Gosling led a team of researchers, in order to produce a new language for the electronic devices used, and in 1991 he began working on preparing the language, and after a long period of time had passed, the team's attention turned to Focusing on the World Wide Web, and in 1995 Java was launched for the first time, and the Java language was able to show interaction and multimedia playback with the Web.

In the late nineties, the Java language transferred multimedia to the Internet, and then began to grow outside the scope of the Internet, including cellular devices, and various computers, and for the large number of Java users, the company developed different types of Java languages, so that these types serve purposes various, including:

Java "SE" for home computers.
Java ME for embedded devices.
Java EE for Internet servers and supercomputers.

Note: In 2010, Oracle Corporation took over the management of Java.

How the Java language works

The way the Java language works differs from other programming languages, as the code is translated into specific instructions for the computer in other languages. Runtime Environment / JRE), or the Java virtual machine (in English: the Java virtual machine), where the (JRE) program acts as a virtual computer, interprets the bitcodes, and translates them for the computer, and it should be noted here that the code can be written in Java for several programs, and this It means writing once, and running on any device. The process of translating commands takes several hours to download a large number of files.

Java language features

The Java language is used because it has the following features:

Ease of use: The basics of Java work stem from the programming language called (C++), which is characterized by the complexity of syntax, and its inadequacy for some of the requirements of Java, and therefore the design of Java is built on improving the language (C++), and providing powerful and easy-to-use programming.
reliability: Java detects potential errors in the programming system, by collecting manipulated data.
Safety: Java is one of the safest programming languages.
Independence: The Java language is characterized by its independence, as it is not related to the operating system, computer hardware, and the device on which it is installed.

different programming languages

The computer recognizes the information presented to it by writing it in the programming language that the computer understands, and there are many programming languages other than the Java language, the most important of which are:
