Java is a high-level programming language developed by Sun Microsystems and released in the year 1995. Since Java has a runtime environment (JRE) and API which defines that java also a platform. Java is mainly used for Back-end. It works on class-based objects. Java is a platform Independent Language which is executed by the JVM (Java Virtual Machine) that needs to be compiled into "byte-code" and has the file extension "Java".

Why Use Java?

Java runs on a variety of platforms, such as Windows, Mac OS, and several versions of UNIX. It works with the Object-Oriented method because everything is an object in java. This is a Platform Independent language, unlike other languages C and C++, Java doesn't need to be compiled into a specific machine, rather than into an independent byte code. Byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on.
