Applications of Java Programming Language
11:45:00Applications of Java Programming Language
Java language was developed by
Sun Microsystems in 1995. In subsequent years, the language has become the
backbone of millions of applications across multiple platforms including
Windows, Macintosh and UNIX-based desktops, Android-based mobiles, embedded systems
and enterprise solutions. According to Oracle (that acquired Sun Microsystems
in 2010), Java now runs on more than 3 billion devices.
Types of Applications that Run on Java
1. Desktop GUI Applications:
Java provides GUI development through various means like Abstract
Windowing Toolkit (AWT), Swing and JavaFX. While AWT contains a number of
pre-constructed components such as menu, button, list, and numerous third-party
components, Swing, a GUI widget toolkit, additionally provides certain advanced
components like trees, tables, scroll panes, tabbed panel and lists. JavaFX, a
set of graphics and media packages, provides Swing interoperability, 3D graphic
features and self-contained deployment model which facilitates quick scripting
of Java applets and applications.
Eg : Antivirus softwares, Media player, Games, etc..,
2. Mobile Applications:
Java Platform, Micro Edition (Java ME or J2ME) is a cross-platform
framework to build applications that run across all Java supported devices,
including feature phones and smart phones. Further, applications for Android,
one of the most popular mobile operating systems, are usually scripted
in Java using the Android Software Development Kit (SDK) or other
environments.
Eg: Games, Mobile OS, Android OS ,APP & Games, driver programs
3. Embedded Systems:
Embedded systems, ranging from tiny chips to specialized
computers, are components of larger electromechanical systems performing
dedicated tasks. Several devices, such as SIM cards, blue-ray disk players,
utility meters and televisions, use embedded Java technologies.
According to Oracle, 100% of Blu-ray Disc Players and 125 million TV devices
employ Java.
Eg: RTOS, Real time Embedded product programs(eg: ATM Machine, washing machie using Embedded java coding).
4. Web Applications:
Java provides support for web applications through Servlets,
Struts or JSPs. The easy programming and higher security
offered by the programming language has allowed a large number of government
applications for health, social security, education and insurance to be based
on Java. Java also finds application in development of eCommerce web
applications using open-source eCommerce platforms, such as Broadleaf.
Eg : Dynamic web applications like Shoping websites, Online Games, ONline Chatting applications., etc
5. Web Servers and Application Servers:
The Java ecosystem today contains multiple Java web servers and
application servers. While Apache Tomcat, Simple, Jo!, Rimfaxe Web Server
(RWS) and Project Jigsaw dominate the web server space, WebLogic, WebSphere,
and Jboss EAP dominate commercial application server space.
Eg: Server based distributed applications like LAN,WAN, using java supported servers.
6. Enterprise Applications:
Java Enterprise Edition (Java EE) is a popular platform that
provides API and runtime environment for scripting and running enterprise
software, including network applications and web-services. Oracle claims Java
is running in 97% of enterprise computers. The higher performance
guarantee and faster computing in Java has resulted in high frequency trading
systems like Murex to be scripted in the language. It is also the backbone for
a variety of banking applications which have Java running from front user end
to back server end.
Eg : Banking softwares, ERP's, etc.,
7. Scientific Applications:
Java is the choice of many software developers for writing
applications involving scientific calculations and mathematical operations.
These programs are generally considered to be fast and secure, have a higher
degree of portability and low maintenance. Applications like MATLAB use Java
both for interacting user interface and as part of the core system.
In conclusion, Java is widely applicable across different types of
applications. It offers cross-functionality and portability, and
these features, among many others, make Java the programming language of choice
for software development of a specific nature.
