It is been seen that current programming problems are complex. Structured
programming cannot manage complexity of complex programs. Obeject
Oriented Programming makes it possible to organise large and complex
programs using classes, objects, inheritance, polymorphism and
encapsulation. C++ for years was most widely used OOP language. Due to
advent of internet, Java became widely used and gained tremendous
Java came as the programming language which was widely used in the
consumer electronic devices such as microwaves, television etc. A lot of
research was been done to build a small, reliable, processor independent,
real-time, safe and distributed software for these systems. With the
coming of Internet and WWW, Java went on becoming a full fledged
programming language, shifting its focus from consumer devices to a vast
platform to create powerful, distributed, robust and secure applications.
A Brief History Of Java
Java Programming Language was conceived by the effort of 5 great people,
James Gosling, Patrick Naughton, Chris Warth, Mike Sheridan and Ed Frank.
They all worked for Sun Microsystems, Inc and came up with Java in 1991.
The language took 18 months to develop and had a initial name as "Oak"
which was renamed to Java in 1995, due to copyright issues.
The idea was to develop a language which was platform-independent and
which could create embedded softwares for consumer electronic devices. C
and C++ were quite inefficient for the purpose because they were not
platform-independent as there 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. So the team of 5 also
called as Green Team began to work in developing a easier and cost-
efficient solution. They worked for 18 months in developing a portable,
platform-independent language that could create a code which can run on
variety of processors under differing environments.
The above necessity led to creation of Java. At the same time, Internet
and WWW were becoming popular day-by-day. The web programs lacked the
features of platform-independence. 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 forcus of Java was shifted 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.
