James Gosling and the Green Team at Sun Microsystems developed the Java programming language in 1991, originally calling it Oak. In 1995 it was renamed to Java. Java is a platform independent language that allows web pages to be more dynamic and responsive using Java applets. It typically offers editions for client-side, server-side, and mobile applications. Key features of Java include being simple, object-oriented, platform independent, secure, robust, and portable.

5. ▰ Java is also regarded as Internet
programming language. It can make web
pages more dynamic, responsive using Java
applet whereas HTML is mostly flat & static.
▰ Java typically offers three editions: SE
(Client-side apps.), EE (Server-side apps.) and
ME (apps. for mobile devices)
