If you lot are a beginner as well as only started learning Java, you lot mightiness live thinking where exactly Java is used? You don't come across many games written inwards Java except Minecraft, desktop tools similar Adobe Acrobat, Microsoft Office are non written inwards Java, neither is your operating systems similar Linux or Windows, then where exactly people utilization Java? Does it have got whatsoever real-world application or not? Well, you lot are non alone, many programmers enquire this query earlier starting amongst Java, or afterwards picking Java is ane of the programming linguistic communication of selection at the graduate level. By the way, you lot tin acquire a clue of where Java is used past times installing Java at your desktop, Oracle says to a greater extent than than iii billion devices run Java, that's a huge number, isn't it? Most major companies utilization Java inwards ane agency or other. Many server-side applications are written inwards Java to procedure tens of millions of requests per day, high-frequency trading applications are also written inwards Java e.g. LMAX trading applications, which is built over their path-breaking inter-thread communication library, Disruptor. In this article, nosotros volition come across to a greater extent than precisely, what sort of projects are done inwards Java, which domain or sector Java is dominating as well as where exactly Java is used inwards real-world?
1) Android Apps
If you lot desire to come across where Java is used, you lot are non besides far away. Open your Android band as well as whatsoever app, they are genuinely written inwards Java programming language, amongst Google's Android API, which is similar to JDK. Couple of years dorsum Android has provided much needed boost as well as today many Java programmer are Android App developer. By the agency android uses dissimilar JVM as well as dissimilar packaging, every bit nosotros have got seen inwards our previous article most how Android app works, but code is withal written inwards Java.
2) Server Apps at Financial Services Industry
Java is real large inwards Financial Services. Lots of global Investment banks similar Goldman Sachs, Citigroup, Barclays, Standard Charted as well as other banks utilization Java for writing forepart as well as dorsum role electronic trading system, writing short town as well as confirmation systems, information processing projects as well as several others. Java is by as well as large used to write server side application, by as well as large without whatsoever forepart end, which receives information shape ane server (upstream), procedure it as well as sends it other procedure (downstream). Java Swing was also pop for creating thick customer GUIs for traders, but straightaway C# is rapidly gaining marketplace position portion on that infinite as well as Swing is out of its breath.
3) Java Web applications
Java is also large on due east commerce as well as spider web application space. You have got a lot of RESTfull services beingness created using Spring MVC, Struts 2.0 as well as similar frameworks. Even uncomplicated Servlet, JSP as well as Struts based spider web applications are quite pop on diverse authorities projects. Many of government, healthcare, insurance, education, defence as well as several other subdivision have got their spider web application built inwards Java.
4) Software Tools
Many useful software as well as evolution tools are written as well as developed inwards Java e.g. Eclipse, InetelliJ Idea as well as Netbans IDE. I mean value they are also most used desktop applications written inwards Java. Though at that spot was fourth dimension when Swing was real pop to write thick client, by as well as large inwards fiscal service sector as well as Investment banks. Now days, Java FX is gaining popularity but withal it is non a replacement of Swing as well as C# has almost replaced Swing inwards Finance domain.
5) Trading Application
Third political party trading application, which is also portion of bigger fiscal services industry, also utilization Java. Popular trading application similar Murex, which is used inwards many banks for forepart to depository fiscal establishment connectivity, is also written inwards Java.
6) J2ME Apps
Though advent of iOS as well as Android almost killed J2ME market, but withal at that spot is large marketplace position of depression goal Nokia as well as Samsung handset which uses J2ME. There was fourth dimension when almost all games, application, which is available inwards Android are written using MIDP as well as CLDC, portion of J2ME platform. J2ME is withal pop on products similar Blu-ray, Cards, Set give boxes etc. One of the argue of WhatsApp beingness then pop is because it is also available inwards J2ME for all those Nokia handset which is withal quite big.
7) Embedded Space
Java is also large inwards the embedded space. It shows how capable the platform is, you lot only require 130 KB to live able to utilization Java technology scientific discipline (on a smart carte du jour or sensor). Originally Java was designed for embedded devices. In fact, this is the ane area, which was portion of Java's initial drive of "write once, run anywhere" as well as looks similar it is paying upwards now.
8) Big Data technologies
Hadoop and other large information technologies are also using Java inwards ane agency or other e.g. Apache's Java-based HBase and Accumulo (open source), as well as ElasticSearch as well. By the Java is non dominating this space, every bit at that spot are technologies similar MongoDB which is written inwards C++. Java has potential to acquire major portion on this growing infinite if Hadoop or ElasticSearch goes big.
9) High Frequency Trading Space
Java platform has improved its surgery characteristics a lot as well as amongst modern JITs, its capable of delivering surgery at C++ level. Due to this reason, Java is also pop on writing high surgery systems, because Though surgery is piddling less compared to native language, but you lot tin compromise safety, portability as well as maintainability for to a greater extent than speed as well as it only takes ane inexperienced C++ programmer to brand an application tiresome as well as unreliable.
10) Scientific Applications
Nowadays Java is ofttimes a default selection for scientific applications, including natural linguistic communication processing. Main argue of this is because Java is to a greater extent than safe, portable, maintainable as well as comes amongst amend high-level concurrency tools than C++ or whatsoever other language.
In 1990s Java was quite large on Internet due to Applet, but over the years, Applet's lost its popularity, mainly due to diverse security issues on Applet's sand boxing model. Today desktop Java as well as Applets is almost dead. Java is past times default Software industries darling application evolution language, as well as given its heavy usage inwards fiscal services industry, Investment banks as well as E-commerce spider web application space, whatsoever ane learning Java has vivid time to come ahead of him. Java 8 has only reinforced the belief that Java volition continuing dominating software evolution infinite for years to come.

Real World Java Applications
There are many places where Java is used inwards existent world, starting from commercial e-commerce website to android apps, from scientific application to fiscal applications similar electronic trading systems, from games similar Minecraft to desktop applications similar Eclipse, Netbeans, as well as IntelliJ, from an opened upwards rootage library to J2ME apps etc. Let's come across each of them inwards to a greater extent than detail.1) Android Apps
