Java Programming Language was developed with the combined effort from 5 great geeks, James Gosling, Patrick Naughton, Chris Warth, Mike Sheridan and Ed Frank, while they all were working for Sun Microsystems, Inc. The first public release version of java came in 1991. It took around 18 months combined effort to develop and had a initial name as “Oak” which was renamed to Java in 1995, due to copyright issues.
The core idea behind java was to develop a language that is platform-independent and can be used in various devices such as embedded software’s for consumer electronic devices. C and C++ were quite inefficient for the purpose because they were platform dependent, as their programs have to be compiled for particular hardware before execution. Also, the compiled code was inefficient for other processors and it had to be recompiled. The team of 5 also called as Green Team began to work in developing a easier and efficient, portable and platform-independent language that could create a code which can run on variety of processors under differing environments. That’s how JAVA began!
During late 90s, the Internet and WWW infrastructure become popular day-by-day, and most of the web application was using CGI for programming for web application development. Due to various lags and drawbacks such as platform independency, multi threading and concurrency, CGI was not efficient enough for web applications. It required programs that could run on any operating system irrespective of hardware and software configuration. It required small and portable programs that could be securely transported over the network. The programming language available to suit such requirements was Java.
Many developers soon realized that architectural neutral language like Java would be best for writing programs for Internet. Thus focus shifted towards Java from consumer electronics to World Wide Web.
Today, Java is not an ordinary programming language. It is a technology which is simple, Object Oriented, Distributed, Robust, Secure, Architecture neutral, Portable, Interpreated, Multithreaded, High Performance and Dynamic.
