Java is used widely in various domains including Android apps, server-side applications, web applications, software development tools, trading applications, embedded systems, scientific applications, and high frequency trading. Some major uses of Java include powering Android apps, financial services applications, backend server applications, IDEs like Eclipse and IntelliJ, and trading software. Java remains popular for applications that require performance, reliability, security and cross-platform capabilities.

2. Introductuion:
In the event that you are a learner and simply begun learning Java, you may
be supposing where precisely Java is utilized? You don't see numerous
diversions written in Java with the exception of Mine craft, desktop devices
like Adobe Acrobat, Microsoft Office are not composed in Java, nor is your
working frameworks like Linux or Windows, so where precisely individuals
use Java?
Does it have any true application or not? All things considered, you are not
the only one, numerous software engineers pose this question before
beginning with Java, or subsequent to picking Java is one of the
programming dialects of decision at graduate level.
Coincidentally, you can obtain some much needed education of where Java
is utilized by introducing Java at your desktop, Oracle says more than 3
billion gadgets run Java that is enormous number, would it say it isn't? Most
significant organizations use Java in one way or other

3. Numerous server side applications are
composed in Java to process countless
solicitations every day, high recurrence
exchanging applications are likewise
composed in Java e.g. LMAX
exchanging applications, which
is fabricated over their way breaking
between string correspondence library, Disruptor.
In this article, we will see all the more definitely, what sort of undertakings are
done in Java, which area or division Java is ruling and where precisely Java
is helpful in true?

4. Certifiable Java Applications
There are numerous spots where Java is utilized as a part of certifiable,
beginning from business e-trade site to android applications, from
investigative application to money related applications like electronic
exchanging frameworks, from recreations like Mine craft to desktop
applications like Eclipse, Net beans and IntelliJ, from open source library to
J2ME applications and so on. How about we see each of them in more
detail.
Android Apps
On the off chance that you need to see where Java is utilized, you are not
very far away. Open your Android telephone and any application; they are
really composed in Java programming dialect, with Google's Android API,
which is like JDK. Couple of years back Android has given abundantly
required help and today numerous Java software engineer are Android App
designer. By the way android utilizes diverse JVM and distinctive bundling,
as we have found in our past article about how Android application
functions, yet code is still composed in Java.

5. Server Apps at Financial Services Industry
Java is huge in Financial Services. Bunches of worldwide Investment banks
like Goldman Sachs, Citigroup, Barclays, Standard Charted and different
banks use Java for composing front and back office electronic exchanging
framework, written work settlement and affirmation frameworks, information
preparing activities and a few others. Java is for the most part used to
compose server side application, generally with no front end, which gets
information shape one server (upstream), prepare it and sends it different
procedure (downstream). Java Swing was additionally prominent for making
thick customer GUIs for brokers, yet now C# is rapidly picking up piece of the
overall industry on that space and Swing is out of its breath.
Java Web applications
Java is likewise enthusiastic about E trade and web application space. You
have a considerable measure of Restful administrations being made utilizing
Spring MVC, Struts 2.0 and comparative structures. Indeed, even
straightforward Servlet, JSP and Struts based web applications are very
prevalent on different government ventures. A number of government,
medicinal services, protection, training, safeguard and a few other offices
have their web application fabricated in Java.

6. Software Tools
Numerous helpful programming and advancement devices are composed
and grew in Java e.g. Shroud, InetelliJ Idea and Netbans IDE. I think they
are additionally most utilized desktop applications composed as a part of
Java. In spite of the fact that there was time when Swing was exceptionally
well known to compose thick customer, for the most part in monetary
administration segment and Investment banks. Presently days, Java FX is
picking up ubiquity yet it is not a substitution of Swing and C# has
practically supplanted Swing in Finance space.
Trading Application
Outsider exchanging application, which is likewise piece of greater
monetary administrations industry, additionally utilizes Java. Mainstream
exchanging application like Murex, which is utilized as a part of numerous
banks for front to bank integration, is additionally composed in Java.

7. J2ME Apps
In spite of the fact that appearance of iOS and Android practically murdered
J2ME market, yet at the same time there is extensive business of low end
Nokia and Samsung handset which utilizes J2ME. There was time when all
recreations, application, which is accessible in Android, are composed
utilizing MIDP and CLDC, some piece of J2ME stage. J2ME is still prevalent
on items like Blu-beam, Cards, Set top boxes and so on. One of the reasons
of WhatsApp being so mainstream is on account of it is additionally
accessible in J2ME for each one of that Nokia handset which is still
enormous.
Embedded Space
Java is likewise enormous in the inserted space. It demonstrates how
competent the stage is, you just need 130 KB to have the capacity to utilize
Java innovation (on a brilliant card or sensor). Initially Java was intended for
installed gadgets. Truth be told, this is the one territory, which was a piece of
Java's introductory crusade of "compose once, run anyplace" and seems as
though it is paying up now.

8. Big Data advances
Hadoop and other enormous information advances are likewise utilizing
Java as a part of restricted or other e.g. Apache's Java-based HBase and
Accumulate (open source), and Elastic Search too. By the Java is not ruling
this space, as there are advances like Mongo DB which is composed in
C++. Java can possibly get significant share on this developing space if
Hadoop or Elastic Search goes huge.
High Frequency Trading Space
Java stage has enhanced its execution attributes a great deal and with
advanced JITs, its equipped for conveying execution at C++ level. Because
of this reason, Java is likewise prevalent on composing elite frameworks, in
light of the fact that though execution is minimal less contrasted with local
dialect, however you can bargain security, versatility and practicality for
more speed and it just takes one unpracticed C++ developer to make an
application moderate and untrustworthy.

9. Scientific Applications
These days Java is frequently a default decision for exploratory applications,
including normal dialect handling. Fundamental reason of this is on account
of Java is more protected, versatile, viable and accompanies better
abnormal state concurrency instruments than C++ or whatever other dialect.
In 1990s Java was enthusiastic about Internet because of Applet, yet
throughout the years, Applet's lost its ubiquity, for the most part because of
different security issues on Applet's sand boxing model. Today desktop Java
and Applets is dead. Java is of course Software commercial enterprises
sweetheart application advancement dialect, and given its overwhelming
use in money related administrations industry, Investment banks and E-
business web application space, any one learning Java has brilliant future in
front of him. Java 8 has just fortified the conviction that Java will keeping
commanding programming improvement space for a considerable length of
time to come.
