Where Is Coffee Used Inwards Existent World?
If you lot are a beginner in addition to but started learning Java, you lot mightiness live thinking where exactly Java is used? You don't encounter 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 purpose Java? Does it conduct hold whatever real-world application or not? Well, you lot are non alone, many programmers inquire this query earlier starting amongst Java, or later on picking Java is ane of the programming linguistic communication of pick 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 purpose Java inwards ane agency or other. Many server-side applications are written inwards Java to physical care for 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 encounter to a greater extent than precisely, what sort of projects are done inwards Java, which domain or sector Java is dominating in addition to where exactly Java is used inwards real-world?
1) Android Apps
If you lot desire to encounter where Java is used, you lot are non also far away. Open your Android telephone in addition to whatever app, they are truly 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 in addition to today many Java programmer are Android App developer. By the agency android uses dissimilar JVM in addition to dissimilar packaging, equally nosotros conduct hold seen inwards our previous article well-nigh how Android app works, but code is yet written inwards Java.
2) Server Apps at Financial Services Industry
Java is really large inwards Financial Services. Lots of global Investment banks similar Goldman Sachs, Citigroup, Barclays, Standard Charted in addition to other banks purpose Java for writing front end in addition to dorsum constituent electronic trading system, writing village in addition to confirmation systems, information processing projects in addition to several others. Java is to a greater extent than oft than non used to write server side application, to a greater extent than oft than non without whatever front end end, which receives information shape ane server (upstream), physical care for it in addition to sends it other physical care for (downstream). Java Swing was also pop for creating thick customer GUIs for traders, but forthwith C# is speedily gaining marketplace part on that infinite in addition to Swing is out of its breath.
3) Java Web applications
Java is also large on due east commerce in addition to spider web application space. You conduct hold a lot of RESTfull services existence created using Spring MVC, Struts 2.0 in addition to similar frameworks. Even uncomplicated Servlet, JSP in addition to Struts based spider web applications are quite pop on diverse authorities projects. Many of government, healthcare, insurance, education, defence in addition to several other subdivision conduct hold their spider web application built inwards Java.
4) Software Tools
Many useful software in addition to evolution tools are written in addition to developed inwards Java e.g. Eclipse, InetelliJ Idea in addition to Netbans IDE. I intend they are also most used desktop applications written inwards Java. Though at that spot was fourth dimension when Swing was really pop to write thick client, to a greater extent than oft than non inwards fiscal service sector in addition to Investment banks. Now days, Java FX is gaining popularity but yet it is non a replacement of Swing in addition to C# has almost replaced Swing inwards Finance domain.
5) Trading Application
Third political party trading application, which is also constituent of bigger fiscal services industry, also purpose Java. Popular trading application similar Murex, which is used inwards many banks for front end to banking company connectivity, is also written inwards Java.
6) J2ME Apps
Though advent of iOS in addition to Android almost killed J2ME market, but yet at that spot is large marketplace of depression halt Nokia in addition to Samsung handset which uses J2ME. There was fourth dimension when almost all games, application, which is available inwards Android are written using MIDP in addition to CLDC, constituent of J2ME platform. J2ME is yet pop on products similar Blu-ray, Cards, Set exceed boxes etc. One of the argue of WhatsApp existence then pop is because it is also available inwards J2ME for all those Nokia handset which is yet quite big.
7) Embedded Space
Java is also large inwards the embedded space. It shows how capable the platform is, you lot only postulate 130 KB to live able to purpose Java applied scientific discipline (on a smart bill of fare or sensor). Originally Java was designed for embedded devices. In fact, this is the ane area, which was constituent of Java's initial crusade of "write once, run anywhere" in addition to looks similar it is paying upward 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), in addition to ElasticSearch as well. By the Java is non dominating this space, equally at that spot are technologies similar MongoDB which is written inwards C++. Java has potential to acquire major part on this growing infinite if Hadoop or ElasticSearch goes big.
9) High Frequency Trading Space
Java platform has improved its surgical physical care for characteristics a lot in addition to amongst modern JITs, its capable of delivering surgical physical care for at C++ level. Due to this reason, Java is also pop on writing high surgical physical care for systems, because Though surgical physical care for is picayune less compared to native language, but you lot tin compromise safety, portability in addition to maintainability for to a greater extent than speed in addition to it only takes ane inexperienced C++ programmer to brand an application tiresome in addition to unreliable.
10) Scientific Applications
Nowadays Java is oft a default pick for scientific applications, including natural linguistic communication processing. Main argue of this is because Java is to a greater extent than safe, portable, maintainable in addition to comes amongst ameliorate high-level concurrency tools than C++ or whatever 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 in addition to Applets is almost dead. Java is past times default Software industries darling application evolution language, in addition to given its heavy usage inwards fiscal services industry, Investment banks in addition to E-commerce spider web application space, whatever ane learning Java has vivid futurity 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, in addition to IntelliJ, from an opened upward beginning library to J2ME apps etc. Let's encounter each of them inwards to a greater extent than detail.1) Android Apps
If you lot desire to encounter where Java is used, you lot are non also far away.
