History of java
Earlier they wanted to name Java as Oak, but Oak was already registered by some other company, so it could not be registered, then the team decided to name it Java.
At that time sun microsystems got a project to build a software for set-top box but at that time no suitable computer programming language available.
So the people of Sun Microsystem decided to make a new language which can work on all OPERATING SYSTEM but it was not possible,
that's why they made a platform of his own and made a new language for that platform, which became very popular going forward, today we know that platform as JDK and that language like java.
