What is Java?

Java is an object-oriented, robust, secured and platform-independent programming language. With the help of Java Programming, we can develop console, window, web, enterprise and mobile applications.

Java language was developed in 1995 by James Gosling who is known as the father of Java. The first version of Java released on 23rd January, 1996.

There are three editions of Java: Java SE (Java Standard Edition), Java EE (Java Enterprise Edition), and Java ME (Java Micro Edition).
