introduction of java language

Java is a high-level, third generation programming language,
like C, FORTRAN, Smalltalk, Perl, and many others. You can use
Java to write computer applications that play games, store data or
do any of the thousands of other things computer software can do.
Compared to other programming languages, Java is most similar to
C. However although Java shares much of C's syntax, it is not C.
Knowing how to program in C or, better yet, C++, will certainly help
you to learn Java more quickly, but you don't need to know C to
learn Java. A Java compiler won't compile C code, and most large
C programs need to be changed substantially before they can
become Java programs. What's most special about Java in relation
to other programming languages is that it lets you write special
programs called applets that can be downloaded from the Internet
and played safely within a web browser. Java language is called as
an Object-Oriented Programming language and before begining for
Java, we have to learn the concept of OOPs(Object-Oriented
Programming).

Basic concept of OOPS
There are some basic concepts of object oriented programming as
follows:
1. Object
2. Class
3. Data abstraction
4. Data encapsulation
5. Inheritance
6. Polymorphism
7. Dynamic binding

JAVA HISTORY :

Java is a general-purpose, object-oriented programming
language developed by Sun Microsystems of USA in
1991.Originally called Oak by James Gosling (one of the inventor of
the language). Java was invented for the development of software
for cunsumer electronic devices like TVs, tosters, etc. The main aim
had to make java simple, portable and reliable.
Java Authors: James , Arthur Van , and others

Following table shows the year and beginning of Java.
YearProgress
1990Sun decided to developed software that could be used for electronic devices. And the project called as Green Project head by James Gosling.
1991Announcement of a new language named “Oak”
1992The team verified the application of their new language to manage a list of home appliances using a hand held device.
1993The World Wide Web appeared on the Internet and
transformed the text-based interface to a graphical rich environment.
1994The team developed a new Web browsed called “Hot Java” to locate and run Applets.
1995Oak was renamed to Java, as it did not survive “legal” registration. Many companies such as Netscape and Microsoft announced their support for Java.
1996Java language is now famous for Internet
programming as well as a general purpose OO
language.
1997Sun releases Java Development Kit(JDK 1.1)
1998Sun releases Software Development Kit (SDK 1.2)
1999Sun releases Java 2 platform Standard Edition (J2SE) and Enterprise Edition(J2EE).
2000J2SE with SDK 1.3 was released.
2002J2SE with SDK 1.4 was released.
2004J2SE with JDK 5.0 was released.
