A bit of history
Java is a programming language that was born in year 1995 by the company Sun Microsystems. The language in its beginning was called Oak (oak in English), since from the office it became a great oak, but finally it was renamed Java.
In 2010 Oracle (one of the big shots of technology companies) buys this company and takes Java.
The name is suspected to come from the initials of his disabled: James Gosling, Arthur Van Hoff and Andy Bechtolshei.
