The creation of JAVA:

The creation of JAVA:(part 1)


JAVA was conceived by James gosling,Patrick Naughton, Chris wrath, ed frank, and Sheridan at sun micro systems,Inc.in 1991.It took 18 months to develop first working version.This language is initially called "OAK", but later it is changed to "JAVA" in 1995. Between the initial implementation of OAK in the fall of 1992 and the public announcement of JAVA in the spring of 1995, Many more people contributed to design and evolution of the language. Bill joy, Arthur van Hoff, Jonathan Payne, Frank Yellin, and Tim Lindholm were key contributors to the maturing of the original prototype.
        Somewhat surprisingly, the original impetus for JAVA was not on internet!Instead , the primary motivation was need for platform-independent language that could be used to create software to embed on various consumer devises like Micro waves ovens, Dish washers, Remote controls etc,.Generally,there is a statement that "The electronic world runs on JAVA".As you can probably guess , many types of CPUs are used as controllers. The trouble with C and C++(and most other languages) is that they are designed to be compiled for a specific target. Although it is possible to compile C++ program for just about any type of CPU, to do so it requires a full C++ compiler targeted for that CPU.The problem is that compilers are expensive and time consuming to create. An easier- and more cost efficient-solution was needed. In an attempt to find such a solution,Gosling and others began work on portable, platform-independent language could be used to produce a code that would run on variety CPUs under differing environments. This effort
ultimately led to the creation of JAVA
