What is the java language

Java language

Java is a high-level programming language developed by James Gosling of Sun MicroSystems while trying to develop the C++ programming language in 1991. It was called (OAK), but in 1995 Sun Micro Systems modified it. And I called it Java, and it's an object-based language.

Java versions

There are several versions of Java, namely:

• (Java Standard Edition): The standard version used for programming desktop programs.
• (Java Enterprise Edition) It is used for programming servers and the web.
• (Java Micro Edition) is specialized in programming mobile phones and limited devices, especially games.

Characteristics and advantages of Java

• The Java language is an easy language to prepare various applications, because it contains many features that make it easier for the programmer to work, as it provides direct communication with databases, multiple inheritance, and others.
• Robust, bug-free applications can be programmed using Java, and errors can be modified during programming.
• Safe, it works through its virtual environment, adopts risk management, and adopts encryption.
• Java works on several operating systems, such as Windows, Macintosh, and Unix in all its versions.
• It is possible to write programs that carry out more than one task at the same time, thanks to the (Multi-threaded) feature.
• Applications and programs written in Java run quickly. Because java processing is fast.
• Adding sound and animations to web pages.

Important terms in Java

• object: An object with states and behaviors created from a class.
• Example: The horse has a state: a name, a color, and a behavior: such as running, whinnying, and it belongs to the class of mammals.

• (class) A class can be defined as a template that describes the behaviors and state of the object to which it belongs.
• (Methods): They are basically behaviors, and the (class) contains a set of (methods) through which the data is processed.
• Instance Variables Each object has its own unique set of variables, and the state is created by these variables.
• Inheritance: Through Java, you can build a class using another class, if you want to take advantage of (methods) in an existing class without the need to rewrite the code sentences for those (methods), which reduces programming time, and reduces From the code of the application.
• Interfaces: Interfaces, defined in the Java language as a contract that shows how objects communicate with each other, and they are very important with regard to inheritance.
• (Constructors): One of the most important terms related to (class), when it is created, its (constructor) is called, and it can be more than one, and the name of (constructor) must be identical to the name of its (class).

Java has a very wide spread around the world, as it interferes with most modern technologies, especially the web.
