The Java Programming Language was developed on May 23, 1995, by James Gosling. It has been the world’s first or second most widely used programming language since 2001, according to Tiobe. The Java name is derived from the Just Another Vague Acronym. Java is available for free and can be considered one of the most efficient high-level programming languages. This article will explain how to setup Java on Ubuntu 21.04 and familiarize you with some essential features.

Introduction to Java

Java is a computer programming language by which programmers can program without having to write numerical code and by writing English commands and you can use it on different applications of VPS and dedicated servers. It is a high-level language because humans can easily read and write. It is also an object-oriented programming language similar to C and C ++ languages, but much more convenient. At first, it was only intended for mobile devices, but its use has multiplied with the development of the Internet and the web for web browsers and website programming. Let me make this brief point, it was supposed to be called OAK, but later changed its name to Java, and the logo of this programming language was due to the interest of its development team in coffee.
