Overview:

Java could also be a programming language and a computing platform for application development. It is class-based, object-oriented, and designed to possess as few implementation dependencies as possible. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle) and released in 1995 as a core component of Sun Microsystems' Java platform. It is almost like C and C++ but tons easier. You'll combine Java with plenty of technologies like spring, node Js, Android, Hadoop, J2EE, etc. to make robust, scalable, portable and distributed full-fledged applications. Java also promotes continuous integration and testing using tools like Selenium.

Java applications are typically compiled to bytecode which can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.
