Oak (programming language)

Oak is a discontinued programming language created by James Gosling in 1989, initially for Sun Microsystems' set-top box project. The language later evolved to become Java.
The name "Oak" was used by Gosling after an oak tree that stood outside his office.
History.
In 1995, Sun Microsystems was attempting to develop a new technology for programming next generation smart appliances, which Sun expected to be a major new opportunity.
The team originally considered using C++, but rejected the idea for several reasons (see Java history).
Initially, Gosling attempted to modify and extend C++ but soon abandoned that in favor of creating a new platform called "Green" and an entirely new language, which he called Oak, after the tree that stood just outside his office.
By the summer of 1992, they were able to demonstrate portions of the new platform including the Green OS, the Oak language, the libraries, and the hardware. Their first attempt, demonstrated on September 3, 1992, focused on building a PDA device named "Star7" which had a graphical interface and a smart agent called "Duke" to assist the user.
Oak was renamed "Java" in 1994 after a trademark search revealed that "Oak" was used by Oak Technology. Java 1.0 was finally shipped in 1996.
Differences with Java.
Oak was the basis for what Java 1.0 became later, but there were also some differences:
Several concepts were planned in the Oak specification but were not implemented in the original language because of time constraints:
Other concepts were different from, or improved later, for Java:
And finally some concepts were later scraped out:
