So open your notepad and NetBeans. Jv compiler. Suppose you don’t have that compiler so that you can download it from our link. We are sharing links to both compilers.
Java is a programming language and a platform. It is a high-level language.
Platform: Any hardware or software environment in which
program runs is
known as platform
so Jv runs on a variety of platforms, such as Windows, Mac OS,
and the various versions of UNIX.
Java is a simple and yet powerful object oriented
programming language
Java code that runs on one platform does
not need to be recompiled to run
on another platform,
it’s called write once,
run anywhere(WORA)
Types of java applications
- Standalone: known as desktop/window based
applications.
We need to install on every machine.
E.g. : media player, antivirus etc.
Swing and AWT are
used for creating standalone .
2. Web: that runs on the server-side and creates a dynamic
page is
called web applications
so Spring, struts, hibernate, JSF technologies used for creating
web applications.
Enterprise:
that is distributed in
nature, such as banking
applications etc.
is called
enterprise application.
so It has advantages of high-level security, load balancing, and
clustering.
E.g. : media player, antivirus etc.
EJB
is used for creating
enterprise applications
4. Mobile:
so mobile devices are
called a mobile
application.
Currently,
Android and Java ME
are used for
creating mobile applications also.
History of java
so java was originally designed for interactive television,
but it was too
advanced technology for the digital cable television industry at the time.
The history of jvstarts with Green Team. team members (also
known as Green Team), initiated this project to develop a language for
digital devices such as set-top boxes, televisions, etc. However, it was
suited for internet programming. Later, technology was
incorporated by Netscape.
so The principles for creating Java programming were “Simple, Robust,
Portable, Platform-independent, Secured, High Performance,
Multithreaded, Architecture Neutral, Object-Oriented, Interpreted
and Dynamic”. therefore
There are given significant
so points that describe
the history of Java.
- James Gosling, Mike Sheridan, and Patric Naughton initiated the Java language project in June 1991 The small team of sun engineers called the Green Team.
Why Oak? Oak is a symbol of
strength and chosen as a national tree of many countries like the U.S.A. France, Germany, Romania, etc
In 1995, Oak was
renamed
as “Java” because it was already a trademark by Oak Technologies.
