3. WHAT IS JAVA
• 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.

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.

6. WHERE IT IS UTILIZED
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.
7. DIFFERENT KINDS OF JAVA APPLICATIONS
• 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.
• Mobile Application
An application that is made for mobile gadgets. As of now Android and Java ME are
utilized for making mobile applications.
8. CONTINUED..
• 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.
