2. JAVA APPLICATIONS
1. Java Desktop GUI Applications:
To develop a GUI application, there are various features like AWT, Java Foundation Classes, Swing
API, and also JavaFX. You bid adieu to older desktop apps and create the latest and advanced 3D-
Grapical apps with these features.
Some examples of real-world desktop GUI apps include AcrobatReader and ThinkFree.
2. Java Web Apps:
Do you want to make something functioning online? Java comes readily to serve that purpose too.
Multiple web development features like Struts, Servlets, Hibernate, JSPs, Spring, etc make our web
pages look stunning.
Here are some real-world tools: Amazon, Wayfair, Broadleaf
3. 3. Java Mobile / Android Apps:
The growth of the smartphone industry has led to the emergence of Android app development as
an inevitable field. The cross-platform framework in Java, J2ME has all the features that are
required to build a smartphone app.
Some mobile apps are:
a. Uber: This app helps people to book cabs and bikes. It helps them share rides without waiting
for cabs and spending scads of time. The security feature in it that allows flawless money
transactions and map features that show the location are all constructed using this programming
language.
b. Netflix: This subscription-based streaming service allows users to pay and binge watch tv
shows and movies 24 x 7. Netflix’s algorithm recommends shows that suit the customers’
preferences. And not to mention, this is possible due to the ability of the programming language
that is used to design it.
4. Java Scientific Apps:
Its robustness and security features have made it rule the field of scientific computing. Tools made
using this language and its simulation environment let us accomplish challenging computational
tasks that require scientific research.
4. 5. Java Financial Sector Applications:
Security stands first when it comes to any financial transaction. As this programming language is
well-known for its safety and security features, it plays a dominant role in the online financial
industry. Apart from online transactions, embedded system software that is used in ATMs also
incorporates Java.
6. Embedded Systems:
Embedded systems are playing a major role in the electronic product industry. Though they
perform only a specific action with limited inputs, accuracy is what is important.
Some Embedded systems are:
a. Voyager: The voyager is well-known to serve its user at the coffee machines and ovens. It
controls and monitors to complete the assigned task successfully. Due to the need for it as GUI
software, developers have used Java in its making process.
b. Nest Thermostat: This device monitors the temperature inside the building and regulates
control remotely. The users or the house owners can keep the room temperature and energy
consumption at their house under control.
5. 7. Java Trading Applications:
Trading apps are most common these days. People who are interested in stocks and make a living
out of it or maintain it as a second income, cannot think of a life without these trading apps these
days. Some such trading apps are:
a. CQG: This app is quite popular in the trading domain for the last two decades. It is a high-
performance trading app that helps common people to analyze and market data. It provides
various details regarding the current price, news, and various other factors.
b. Zen Trader: This trading app created using Java helps people attain wisdom in trading. It is also
highly accessible.
8. Java Enterprise Applications:
The functionality of the enterprise applications is to operate in a corporate environment. Instead of
focusing on an individual user, Enterprise Apps tend to cater to the needs of an organization.
The robust feature present in it, makes it opt for these kinds of software. We cannot deny the fact
that most of these are developed in Java due to the factors like scalability, powerfulness, security,
and so on. On top of that, Oracle proudly claims that 97% of enterprise apps are built using Java.
To be precise, JEE API offers various tools that form a base and critical part of an enterprise
application.
6. 9. Java Gaming Applications:
Game developers make use of Java’s most powerful 3D engine to develop 3D game software. No
other programming language provides such enormous engine capacity that can be used for game
development.
Some of the popular games that are designed with this capacity include Mission Impossible III,
Minecraft, and so on.
The inbuilt framework like LibGDX and OpenGL provide additional functionalities for game
development.
10. Java for Big Data Technologies:
The latest technology dominating these days is Big data technology. It comprises extremely large
and complex datasets that can analyze to extract patterns, trends, and useful information.
In this information age, the Big Data technology field is immensely growing heights.
Big Data technologies like Apache Hadoop, Apache Mahaut, and Apache Spark are some of the
sub-projects.
7. 11. Java for Distributed Applications:
An app or software that runs on multiple computers within a network is termed a distributed
system. The requirement of such systems is common as they are dynamic.
Some of the APIs that are available to develop distributed apps are RMI (Remote Procedure
Invocation) and CORBA (Common Object Request Broker Architecture).
The JINI (Java Intelligent Networking Infrastructure) is a network architecture that allows us to
develop distributed systems. Using the infrastructure that it provides, we can register and search
for distributed services according to the requirements.
12. Java for Cloud-based Applications:
The rise of cloud computing has led to the increased integration of cloud-based and local
components to work simultaneously. The availability of IT resources like online storage,
networking, software, databases, and so on has become common.
The distributed nature lets it play a dominant role in the Cloud computing domain.
Features like Saas (Software-as-a-Service), IaaS (Infrastructure-as-a-Service) and PaaS (Platform-
as-a-Service) are growing heights with the presence of this programming language.
Speaking of the development tools, we cannot avoid the Oracle Java Cloud Service. This platform
lets us easily create, configure and scale the JEE environment in its oracle cloud.
8. 13. Java in Software Tools:
As the name suggests, a software tool is a set of programs that lets a user design, develop,
analyze, debug, maintain, and coordinate with other applications.
To create these software tools, the developers opt for this programming language as it has various
functionalities. Some of the popular software tools that are created are Eclipse, NetBeansIDE,
IntelliJ Idea, and so on.
14. Java for Web Servers and Application Servers:
To publish all the websites and run them, we need a web server. It connects to the internet and
supports the interchange of data to take place over the other devices connected to the internet.
Web servers use the HTTP (Hypertext Transfer Protocol) and the other available protocols to
process client requests and respond to them. All the requests over the WWW (World Wide Web)
are also stored in the web servers.
The application server or the app server lets us host apps via a communication protocol. It holds
the business logic of the app and performs all the required functions.
Web servers built using this language include Apache Tomcat, Simple, Rimfaxe Web
Server(RWS) Apache HTTP server, Project Jigsaw, Resin, etc.
On the other side, some app servers include GlassFish, WebSphere, and WebLogic.
9. CONCLUSION
Java plays a prominent role in almost every app that we use today. Just a
single article would not be enough to elucidate its domination in every
other domain. Despite various programming languages, it stands still with
its strong functionalities. You can try your hands at some of the apps that
were explained in the article and make the most out of them.
