Give a brief historical development of Java.

In 1991, at Sun Microsystems, Green team led by James Gosling started working on a new technology for consumer electronic devices. Over the next 18 months, in 1992 the team created a new programming language which they called “Oak”. By 1994 the team refocussed their efforts towards internet programming with Oak as it didn't find much traction in consumer electronics space. Oak was renamed to Java and on 23rd of May 1995, Sun microsystems made its first public release.
