Appliction of Java Programming 

Language

Our core Java programmingis designed for students and working professionals . Java is an object oriented language, class-based, concurrent, secured and general-purpose computer-programming language. It is a widely used robust technology.

 What is Java?

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.

Java Example

Let’s have a quick look at Java programming example . A detailed description of Hello Java example is available next article.

class simple{

public static void main(string args[]){

system.out.printIn(“Hello Java”);

}

}

Application

According to Sun, 3 billion devices run Java. there are many devices where java is currently used. some of them are as follows:

1.Desktop applications such as acrobat reader, media player, antivirus etc.2.Web applications such as irctc.co.in, javatpoint.com etc.3.Enterprise applications such as banking applications.4.Mobile5.Embedded System6.Smart Card7.Robotics8.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 windwo-based applications. These are traditional software that we need to install on every machine. Example of standalone applications 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, 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 four 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.
