It is very different to C or C++ applications where programs compiled into binaries specific to OS. It makes the Java applications platform-independent. This bytecode can be run in any machine having Java runtime environment (JRE). Platform Independent – The programs written in Java are converted to bytecode first, by Java compiler.

Java provides support for all major object-oriented principles as seen in other object-oriented languages. An object is kind of wrapper that encapsulated data and its associated behavior.

Object Oriented – In Java, everything is represented as objects.

Some of these are unique to Java and some of these are common among other languages. We can read about all the previous Java releases and their features in the linked post.

Java Development Kit (JDK) which is intended for software developers and includes development tools such as the Java compiler, Javadoc, Jar, and a debugger.Java Runtime Environment (JRE) which contains the parts of the Java SE platform required to run Java programs and is intended for end users.The Oracle implementation is packaged into two different distributions: The Oracle implementation is available for Microsoft Windows, Mac OS X, Linux, and Solaris. This implementation is based on the original implementation of Java by Sun. Oracle Corporation is the current owner of the official implementation of the Java SE platform, following their acquisition of Sun Microsystems on January 27, 2010. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform.
