-----------

Java is a programming language and a platform.

Java is a high level, robust, object-oriented and secure programming language.

Platform: Any hardware or software environment in which a program runs, is known as a platform. Since Java has a runtime environment (JRE) and API, it is called a platform.

------

### Application 

-------

    Desktop Applications such as acrobat reader, media player, antivirus, etc.

    Web Applications such as irctc.co.in, javatpoint.com, etc.

    Enterprise Applications such as banking applications.

    Mobile

    Embedded System

    Smart Card

    Robotics

    Games, etc.

--------

### Types of Java Applications

There are mainly 4 types of applications that can be created using Java programming:

##### 1) Standalone Application

Standalone applications are also known as desktop applications or window-based applications. These are traditional software that we need to install on every machine. Examples of standalone application are Media player, antivirus, etc. AWT and Swing are used in Java for creating standalone applications.

##### 2) Web Application

An application that runs on the server side and creates a dynamic page is called a web application. Currently, Servlet, JSP, Struts, Spring, Hibernate, JSF, etc. technologies are used for creating web applications in Java.

##### 3) Enterprise Application

An application that is distributed in nature, such as banking applications, etc. is called enterprise application. It has advantages of the high-level security, load balancing, and clustering. In Java, EJB is used for creating enterprise applications.

##### 4) Mobile Application

An application which is created for mobile devices is called a mobile application. Currently, Android and Java ME are used for creating mobile applications.

----------

### Java Platforms / Editions

-------

There are 4 platforms or editions of Java:

##### 1) Java SE (Java Standard Edition)

It is a Java programming platform. It includes Java programming APIs such as java.lang, java.io, java.net, java.util, java.sql, java.math etc. It includes core topics like OOPs, String, Regex, Exception, Inner classes, Multithreading, I/O Stream, Networking, AWT, Swing, Reflection, Collection, etc.

##### 2) Java EE (Java Enterprise Edition)

It is an enterprise platform which is mainly used to develop web and enterprise applications. It is built on the top of the Java SE platform. It includes topics like Servlet, JSP, Web Services, EJB, JPA, etc.

##### 3) Java ME (Java Micro Edition)

It is a micro platform which is mainly used to develop mobile applications.

##### 4) JavaFX

It is used to develop rich internet applications. It uses a light-weight user interface API.
