What is Java

Java is a general-purpose programming language. It can be used to create applications in various fields: from websites to computer games, from mobile applications to full-fledged programs for corporations and scientific purposes.

The creators have implemented the WORA principle: write once, run anywhere. This means that an application written in Java can be run on almost any platform, which is a great advantage.

Java is also used to work with Big Data, to develop programs for scientific purposes, for example, processing natural languages, devices programming - from household devices to industrial installations. Therefore, this language traditionally has strong positions in industrial programming, in the enterprise segment.

So let's get down to the list

1. NASA World Wind

NASA World Wind belongs to the type of geographic information systems. This is a fully three-dimensional interactive virtual globe that uses NASA satellite imagery and aerial photography of the US Geological Survey to build 3D models of the Earth, Moon, Mars, Venus and Jupiter.

NASA World Wind is an open source proprietary software. The program is written in Java, and runs on all operating systems the OpenGL stack is implemented for.

Initially, the program contains low-resolution maps. When zooming in some area on the map, high-resolution images are downloaded from NASA servers.

The program allows you to select the scale, direction and viewing angle, visible layers, as well as to search by geographical names. The application also has the ability to display the names of geographical objects and political boundaries.

NASA World Wind has an extensible architecture. There are GPS plugins for displaying clouds, earthquakes, hurricanes in near real time and a number of others.

2. Google & Android OS

Google uses Java for many of its products. Mainly for backend programming but also for user interface development.

For example, for Google Docs - a document management application that is very similar to Microsoft Word. But all changes here are saved automatically, and if you are authorized with Google on your devices, you can always open and work with a document everywhere without having to download it.

And of course we cannot but mention the Android OS - after all, it originates from the Java Virtual Machine. Therefore, this language also can be used for mobile applications development.

By the way, regarding the use of Java in Android, the Oracle company, which owns Java, has had a serious conflict with Google. You can read more about this here.

Despite the popularity of Java, many Android developers are already actively switching to Kotlin - another programming language (developed by JetBrains) that runs on top of the JVM and has a number of advantages specifically for mobile development - it is much more concise and less resource-intensive.

3. Netflix

This company and its platform do not need a long introduction. Netflix, one of the largest US entertainment companies, is a provider of movies and TV shows based on streaming multimedia.

The company uses Java for the back end of most of its applications, along with Python. Android and Android TV applications are almost entirely built in Java, with a slight admixture of C ++.

4. Spotify

Spotify is one of the most popular online streaming audio services in the world, allowing users legal and free listening to over 50 million songs, audiobooks, and podcasts. There are web application, desktop application, applications for smartphones and many other smart devices, as well as for car media systems.

Basically, Spotify uses Java and Python to implement some functionality of its web application, for example, to log and stabilize data transfer.

And of course, Java is the main technology for the Spotify application on Android OS.

5. LinkedIn

Today LinkedIn is one of the largest social networks for searching and establishing business contacts. LinkedIn has approximately 600 million registered users representing 150+ business sectors from 200 countries.

Java is one of the main languages of the server side of the platform. It mainly helps to implement the logging functionality, messaging, and also recognize and convert links in texts.

The official LinkedIn mobile app for Android OS is also developed with Java.

6. Uber

For the Uber application, Java is one of the most important technologies along with Python, Node.js and Go. According to the developers, they chose Java precisely because of its high performance, which is one of the main characteristics of this language. Java also has the benefits of an open-source ecosystem and integrates with external technologies such as Hadoop and other analytic tools.

And of course, as in most cases presented earlier, Uber used Java as the main language in the development of its mobile application for the Android operating system.

7. Amazon

Most people know this giant for its huge online e-commerce platform. However, this is far from all that they can offer. In addition to electronic commerce, the main areas of the company include the development and delivery of cloud and streaming solutions, and they also actively develop the AI direction. Amazon is recognized as one of the largest technology companies in the world along with Google, Apple and Facebook.

Mostly, Amazon uses Java for its web services (AWS). They also prefer to write automation scripts in Java, as they are well supported, have many internal tools and environments for developing helper tools.

8. Minecraft

Yes, this world-famous sandbox indie computer game is also written in Java. According to the developers, “Minecraft launcher comes with Java version 1.8.0_51, which is used by default.” However, they recommend upgrading to improve performance.

Unlike many other languages, Java does not run on hardware, but directly on the JVM. In the game, Java is used primarily for building game logic, rendering, and messaging.


All of the above proves the popularity and effectiveness of Java. Although this language has begun to slightly lose its popularity over the past couple of years, the fact that major corporations continue to use it underlines its reliability and good support.

We tried to pick up completely different examples to show you how great Java capabilities are. Hope you enjoyed. If you have some more interesting examples of using Java, comment below.
