What is Java and what does this technology work for?

You have heard about a programming language but you have no idea what it is about, we invite you to stay with us and enjoy the following article on ¿What is Java And what does this technology work for? In which we will give you a summary of the most important aspects.

What is Java ?: Concept

It is a programming language, which is object oriented. Object Oriented Programming (OOP) is a paradigm in programming, being a more efficient way of programming.

It was created with the purpose that the programmer developed the code and it could be executed on various platforms and this is done thanks to the Java virtual machine (JVM).

History

Designed by James Gosling in the early 90s, this element was originally called Oak or Green. This man was named a member of the American National Academy of Engineering (NAE) due to the work carried out in the creation of the language, its compiler and the virtual machine of this language.

In versions 1.1, 1.2 and 1.3, which were the first to be developed, the language was able to take shape thanks to the technologies:

• JBDC (Jamaica Business Development Corporation) and JavaBeans that allowed working with databases.
• RMI (Java Remote Method Invocation), provides the opportunity to use an element remotely.
• AWT (Abstract Window Toolkit), used for graphic creation.
• Collections: Allows you to manage various data structures.
• Java Community Process (JCP): With Java 1.4 it was the first version in which the community participated in its development and this contribution was made through JCP. For the year 2002 version 1.4 is released as JSR 59.
• Java 5: In 2005 the development of version 1.5 of Java began, but in view of the technological scope reached by the language, it was renamed Java 5, from this moment the JDK is identified as version 1.x. In this way JDK 1.5 corresponds to Java 5 and JDK 1.6 to Java 6.
• Java 6: Initially released in 1995 by Sun Microsystems, in this version you could find tools such as: "Script Language Support", they are languages ​​that can be used in order to give instructions to other software.
• JAX-WS (Java API for XML Web Services): It is an API that allows standardization in the creation and use of Web services.
• JDBC.4 (Java Database Connectivity): API that contributes to database activities.
• JAXB (Java Architecture for XML Binding): Makes it easy for programmers to use JAVA in XML structures.
• Java 7: its main attraction is the support of dynamic languages, as well as a new notebook created for file management.

Java 8

It was launched on the market in 2.014, with the main feature of Lambda expression support and the use of Streams, making it one of the most functional programs of the moment, adding the changes in MapReduce.

Thanks to its multiple functions and ease in performing them, they have managed to keep version 8 as the leader compared to the previous ones.

After this, version 9 of this program was released, which is characterized by having Project Jigsaw, in which the JDK and Shell modulation can be established, facilitating work with the RELP8Read-Eval-Print loop style, as well like the support for http 2.0 among others.

Principal function

This programming language is used to develop applications and processes in different types of technological devices.

It is supported by the configuration of objectives, allowing to use a program in different types of operating systems and to use the code remotely in other systems, easily and safely.

In addition, it is designed to be used in both household appliances and mobile phones, but also programmers can use it to create small applications, which are inserted into the HTML code of the page to be viewed and executed in any browser.
