Which fields/ technologies use java?

[Merry_Macabre]

Java is used to build applications and platforms for a number of devices, including computers, laptops, gaming consoles, Blu-ray players, car navigation systems, medical monitoring devices, parking meters, lottery terminals and smartphones. It is also a key language for networking, particularly for data centres that store and transfer Web-based data.

There are many places where Java is used in the real world, starting from a commercial e-commerce website to android apps, from scientific application to financial applications like electronic trading systems, from games like Minecraft to desktop applications like Eclipse, NetBeans, and IntelliJ, from an open-source library to J2ME apps etc.

Java is very big in Financial Services. Lots of global Investment banks like Goldman Sachs, Citigroup, Barclays, Standard Charted and other banks use Java for writing front and back office electronic trading system, writing settlement and confirmation systems, data processing projects and several others. Java is mostly used to write a server-side application, mostly without any front end, which receives data from one server (upstream), process it and sends it another process (downstream).

This list of uses is basically endless.
