Definition and meaning of java

2. Our Java Tutorial or Core Java Tutorial or Java
Programming Tutorial is intended for understudies and
working experts. Java is a question arranged, class-
based, simultaneous, broadly useful computer-
programming language and generally utilized strong
technology. How about we begin taking in Java from
basic inquiries like what is Java, Core Java, where it is
utilized, what kind of applications are made in Java,
why utilize Java and Java platforms and so on. Our
Java instructional exercise encourages you to learn
Java with simple and straightforward cases.

3. Java is a programming language and a platform.
Java is an abnormal state, powerful, secure and
question situated programming language.
Platform: Any equipment or programming condition in
which a program runs, is known as a platform. Since
Java has its own particular runtime condition (JRE) and
API, it is called platform.

4. We should have a snappy take a gander at java
programming case. A nitty-gritty depiction of hi Java
illustration is given in next page.
class Simple{
public static void main(String args[]){

}

5. As indicated by Sun, 3 billion gadgets run java. There
are numerous gadgets where Java is as of now utilized.
Some of them are as per the following:
Work zone Applications, for instance, gymnastic
entertainer peruser, media player, antivirus et cetera.
Web Applications, for instance, irctc.co.in,
javatpoint.com et cetera.
Enterprise Applications, for instance, keeping cash
applications.
Mobile
Installed System
Keen Card
Mechanical independence
Recreations et cetera.

6. There are for the most part 4 kinds of applications that
can be made utilizing java programming:
Standalone Application
• Independent applications are otherwise called work
area applications or window-based applications.
These are customary programming that we have to
introduce on each machine. Case of independent
applications are: Media player, antivirus and so on.
AWT and Swing are utilized as a part of java for
making independent applications.

7. • Web Application
An application that keeps running on the server side and
makes a dynamic page, is called web application. At present,
servlet, jsp, swaggers, spring, sleep, jsf and so on advances
are utilized for making web applications in Java.
• Enterprise Application
An application that is circulated in nature, for example,
keeping money applications and so on is called enterprise
application. It has the upside of abnormal state security,
stack adjusting, and bunching. In Java, EJB is utilized for
making enterprise applications.
• Mobile Application
An application that is made for mobile gadgets. As of now
Android and Java ME are utilized for making mobile
applications.

8. There are 4 platforms or versions of Java:
