What is Java?

Introduction

Java is a powerful object-oriented programming language. It is used to develop desktop and mobile applications, big data processing, embedded systems, and so on. According to Oracle, Java runs on 3 billion devices worldwide, which makes Java one of the most popular programming languages.

Java is fast, reliable, and secure. From desktop to web applications, scientific supercomputers to gaming consoles, cell phones to the Internet, Java is used everywhere.

NoteJava was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java. Before Java, its name was Oak. Since Oak was already a registered company, so James Gosling and his team changed the Oak name to Java.

Java is: –

  • Concurrent where you can execute many statements instead of sequentially executing it.
  • Class-based and an object-oriented programming language.
  • An Independent programming language that follows the logic of “Write once, Run anywhere” i.e. the compiled code can run on all platforms which support java.
