Java is a computing platform and programming language first released in 1995 by Sun Microsystems that is used widely for applications and websites. It is popular because it is free, open source, and can run on any machine with a Java Virtual Machine (JVM). Originally only Java code could run on the JVM, but now other languages like Scala, Groovy, jRuby and Jython can also run on the Java platform. Java is a general purpose, object oriented programming language similar to C++ and C#.

Introduction
Introduction: What Is Java? Java is a computing platform and a programming language that was first released in the year 1995 by Sun Microsystems. Currently, there are a lot of applications and websites that won’t work without Java.
This language is used in almost every domain, including finance, healthcare and logistics etc. Two reasons why Java is so popular are; ?It’s free ?It’s an open source programming language
Java is also a platform, which means that Java code can run on any machine that has a Java Virtual Machine (JVM) on it. Originally those two things were interchangeable, and the only thing that ran on the JVM was Java.
But since that time, a number of languages have been written which can run on the Java platform, languages like Scala, Groovy, an implementation of Ruby called jRuby, and an implementation of Python called Jython.
Java is a general purpose programming language, much like Python or JavaScript. The language itself is specifically an object oriented programming language, so bears similarities to C++, C#.
