Importance of Java applications, Editions and its uses

Importance of JavaWhere Java is used?(Importance of Java and its Uses)

According to Sun, There are 3 billion devices which will run java. Many devices are using Java currently. They are some uses and the importance of Java are:

Importance of Java1. Desktop Applications like media player, antivirus etc run through importance of java.
2. Importance of Java is used for development of Web Applications for indian railways etc.
3. The importance of Java also used for Enterprise Applications for bank applications(e-banking) etc.
4. Mobile Applications
5. Embedded System designing
6. Smart Card (e-cards)
7. It is used for implementation of Robotics
8. It is used for Online Gaming applications etc.

Types of Java Applications and Importance of Java Applications

Mainly there are 4 types of Java applications that are created using java programming:

1) Standalone Application
2) Web Application
3) Enterprise Application
4) Mobile Application

1.  Standalone Application:

Standalone applications are also known as desktop applications. These are also known as window-based applications. These are traditional or conventional softwares that we need to use on every machine. For Example standalone applications are: Media players, antivirus etc. AWT(Abstract Window Toolkit) and Swing are used for creating or building standalone applications in java.

2. Web Application:

An application that runs on the server side and creates dynamic web pages, are called as web applications. At present Servlets, jsp(Java server pages), struts, Spring, Hibernate, jsf (Java Server pages) etc. technologies are used for building web applications in java.

3. Enterprise Application:

Importance of JavaAn application that is distributed in nature or allocated in attributes, that are used for development of banking applications etc. is called enterprise application. Enterprise applications advantages are high level security, load balancing and clustering. EJB(Enterprise JavaBeans) are used for building enterprise applications in java.

4. Mobile Application:

Importance of JavaAn applications that is used for creating or building mobile devices are known as Mobile Applications. At present Android and Java Mobile Edition (J2ME or Java ME) are used for creating mobile applications.

Types of Java Platforms / Editions(Importance of Java Editions)

Generally we discuss only about 3 editions but there are 4 platforms or editions in Java. They are:

1) Java SE (Java Standard Edition)
2) Java EE (Java Enterprise Edition)
3) Java ME (Java Micro Edition)
4) JavaFx

Importance of JavaImportance of Java1) Java SE (Java Standard Edition)

It is a java programming Standard platform. It includes Java programming APIs(Application Programming Interfaces) like java.lang, java.io, java.net, java.util, java.sql, java.math etc. It also includes some core topics like OOPs means Object oriented programming concepts, String, Regex, Exception, Inner classes, Multithreading, I/O Stream, Networking, AWT(Abstract Window Toolkit), Swing, Reflection, Collection etc.

2) Java EE (Java Enterprise Edition)

It is an enterprise platform. It is mainly used for development of web applications and enterprise applications. It is to create top of Java SE platform. In Java, we use topics like Servlet, JSP, Web Services, EJB, JPA etc. for implementing Enterprise applications.

3) Java ME (Java Micro Edition)

It is a micro platform. The importance of java is mainly used for the development of mobile applications.

4) JavaFx

It is a Software Platform and used for creating and developing desktop applications. It is used for the development and importance of java of rich internet applications(RIAs). It uses light-weight user interface that is API(Application User Interface).

Introduction for Java and Overview(History of Java- James Gosling)

Introduction for Java

Introduction for Java

Java is Object oriented language because it supports all oops concepts. We cover the topics that the Introduction for Java and History of Java and its basics.

It is a high level programming language and it is not understandable by machine in introduction for java. Java was firstly developed by Sun Microsystems which was initiated by “James Gosling” and java was released in 1995 as core component of the ‘Sun Microsystems’ Java platform (Java 1.0 [J2SE]) and later it is implemented and undertaken by Oracle. And now we are using or latest version of java is Java 8.0 [J2SE]. There are 2 more versions java 9(older version) and java 10(latest version).

There are three latest J2 versions of java they are:
1. J2SE
2. J2EE
3. J2ME

1. J2SE: It is a Java Standard edition. The latest version of Java Standard edition is Java SE 8.It can work on various types of platforms.
2. J2EE: J2EE means Java Enterprise Edition. It is used for enterprise applications. Java EE are increasing day by day.

Introduction for Java
3. J2ME: J2ME means Java Mobile Edition. It is used for the implementation mobile applications.

Java can run anywhere it is a slogan given by Sun Microsystems “Write once, run anywhere”, or sometimes it maybe “write once, run everywhere”. It was a catchphrase said by Sun Microsystems because they want say benefits of Java programming language.

History and Introduction for Java

Introduction for Java

Java was first initiated by James Gosling. James Gosling originated Java project in June 1991 for use of his many set-top box designs and programs. The Java language, firstly called as ‘Oak’ after an oak tree that stood outside Gosling’s office, also went by the name ‘Green’ and ended up later being renamed as Java, from a list of random words.

Sun Microsystems released first version of Java in 1995 the version is Java 1.0. Java aasured Write Once, Run Anywhere (WORA), it providing no cost and it runs on popular or various types of platforms.

Sun Microsystems announced Java for free and open source software for everyone under the terms of the GNU General Public License (GPL) in 13th November 2006.

On 8th May 2007, Sun Microsystems finished the process and making of all Java’s core code for free and open-source, seperately from a small segment of code to which Sun did not hold the copyright.

James Gosling is known as the “Father of Java“. At present James Gosling is working as chief technology officer at Sun Microsystems. But now java is under taken by Oracle. Java was the first programming language that was designed with internet in mind and which is used to highly distributed applications. Java is First initiates by James Gosling later it is worked by some others.
