Java Introduction

What is Java? Java is an object-oriented programming language, originally launched by Sun Microsystems (now a subsidiary of Oracle) in 1995.

Java is derived from the original features of SmallTalk with a similar syntax to C and C ++. Compared to the 2 languages mentioned, Java is easier to learn because, by its nature, it was designed with the idea of avoiding errors in compiling and allocating memory (unlike C / C ++ which can give you more beats of head).

Uses of Java

The great thing about Java is that it is extremely versatile and can be found in almost any industry. In fact, once you've learned Java programming, you won't miss the uses and applications for it. The most common uses of Java include: web, mobile, and desktop applications.

Mobile applications Android applications can be written entirely in Java, which means you can become an Android developer if you have a good knowledge of Java.

Web applications

Although websites are made with other languages, such as HTML, CSS, and JavaScript, web applications rely on various components that can be written in multiple programming languages. Many web applications rely on server code written in Java. Java also supports the creation of Applets, which are small programs, such as games, that can be run directly in the browser. Desktop applications

Adhering to the "Write once, run anywhere" philosophy, Java can be used to support desktop applications on multiple operating systems, such as Windows, MacOS and Linux. Although Java is not native to any platform, there are a lot of tools that allow you to run Java on any operating system. Oracle, the company that bought Sun Microsystems (the one that created Java), provides tools for developers to write programs in Java on various platforms.

Enterprise applications

Not only is Java a programming language, but it is also a platform. Java EE or Java Enterprise Edition is a special version of the Java platform, designed for business applications. Java EE is often used for large-scale networking and comes with a higher level of security for corporations.

Server applications
v Last but not least, we have Java for servers. In addition to Java EE, Oracle offers JRE Server, which is a Java platform designed specifically for servers. JRE comes from the Java Runtime Environment.
