What is Java?

 

Java is both a platform and a programming language. Programming with Java is high level, reliable, object-oriented, and secure.

Sun Microsystems, a company that is now an Oracle subsidiary, created Java in 1995. The father of Java is thought to be James Gosling. Its previous name was Oak. The name Oak was changed to Java by James Gosling and his team because Oak was already a recognised business.

Platform: A platform is any hardware or software environment in which a programme runs. Java is referred to as a platform since it has a runtime environment (JRE) and an API.
