1. Google Applications

Google is a leading brand that depends on Java for its backend programming and developing interfaces. I’m sure you all are familiar with Google Docs, where you can edit your docs from anywhere on the globe with proper authorization from Google without downloading it. Also, the autosaving functionality too is implemented using Java. 


2. Mobile Industry

Developers turn to Java for building Android-based mobile applications such as Android OS, which they initially developed with Java using Android Development Kit. 

In 2005 since Google took over Android, they chose Kotlin as their app development programing language over Java. Nevertheless, Kotlin calls Java code behind the scenes as Android OS is developed with Java.

Some of the other prominent apps that Java developers have created are Opera Mini which enables private browsing sessions, unlike most other standard browsers. 

3. Social Media Applications

Some popular social media platforms, such as LinkedIn, use 99% Java for their server-side development. Hence, most of the business logic of LinkedIn is written in Java with the Spring/Jetty/Tomcat technical stack. This business logic includes implementing login functionality, converting links into texts, and the chat program.

Furthermore, Java is used to build LinkedIn’s Android OS mobile app.

Other social media apps include parts of Facebook which the creators have used Java to develop as you can not depend entirely on PHP for some sophisticated backend activities.

4. IoT Devices

As the Internet of Things (IoT) has begun significantly impacting people’s lives, did you know that Java is the programming language behind its success? According to a recent survey by Oracle, Java is the most popular language among developers when developing IoT-embedded apps.

Here are some of the top reasons for choosing Java for IoT:

  • It’s platform-independent: This implies that you can run the same app on a desktop and embedded system. So unlike other languages such as C++, the motto of Java is to write once and use it everywhere.
  • Flexibility: Java has a comprehensive library of APIs where the developers would be able to apply them when coding embedded systems. Thus Java negates the need to rewrite these APIs to suit the requirements of embedded systems.
  • Adaptability: When an update is required for an already developed app to run on a new platform, you would be able to perform this transition straightforwardly due to a lack of prone to errors.

5. Enterprise applications 

Another area where organizations heavily use Java is enterprise applications. These gigantic enterprise applications help organizations streamline their workflow, digitize their functionalities, and handle multiple departments. 

Organizations prefer Java due to its tool’s ability to create multi-threaded large-scale enterprise applications. Also, the reliability and secureness of Java play a part.

6. Netflix

Netflix needs no introduction as I’m sure many people like you and I use it for watching movies, TV shows, documentaries, and many more through your handheld devices and laptops. Interestingly, most of its back-end applications are built with Java along with Python.

Once again, Java’s scalability and adaptability to run anywhere are the reasons for choosing Java by their engineers. Additionally, the engineers continuously use Java to capture customer data for analysis to deliver the best user experience for their customers and encode videos. 

7. Trading Applications

Java is also an excellent choice for developing trading applications, where Murex is a principle example. Marex is popular among professional bankers for analyzing risks, treasury, and post-trade processes for financial markets.

The main reason developers prefer Java for these apps over other languages is that they can focus on developing straightforward business logic rather than worrying about incomprehensible memory core dumps, as with C++. 

8. Cloud Applications 

Cloud computing implies on-demand resources via the internet for hosting and maintaining your company resources for a lower cost than you would be compared using in-house resources. 

Java thus provides features that you can use to build applications that you can use in the SaaS, IaaS, and PaaS environments. 

9. Distributed Applications

Distributed applications run on several machines in a network with shared requirements operating in dynamic environments. Java provides APIs such as RMI (Remote Procedure Invocation) and CORBA (Common Object Request Broker Architecture) to construct distributed applications.

The JINI (Java Intelligent Network Infrastructure) provides essential facilities to register and locate distributed services based on location. Then there is Javaspaces, a crucial part of JINI that provides object migration, distribution, and persistence in a distributed context.

10. Software Tools

Developers build software tools or Software Development programs to code, debug and maintain applications ranging from minor to large scale. Some essential software tools include Eclipse, Netbeans, and IntelliJ IDEA, developed in Java.

11. Financial Applications

Most organizations require financial applications to run their daily business operations, such as data-processing, confirmations, and trading systems. Java stands out among other programming languages due to its fraud-proof security features and has a long history with an excellent reputation for building traditional banking applications.  

Also, some leading financial institutions, such as Goldman Sachs and Barclays, use Java-based applications to streamline their business.

12. Self-driven Cars

Certain developed countries are already implementing self-driven cars to make it a reality to see those vehicles on their roads. So if you’re keen on developing these self-driven cars, you need to learn Java. 

Java is one of the major languages used in developing self-driven cars in combination with robotics and Artificial Intelligence.

13. Big Data Industry

Already people are benefiting immensely from Big data technologies, which deal with extracting meaningful information from complex data sets. 

Java programming is one of the technologies behind the success of Big data applications since it consists of features such as memory distribution, garbage collection, and stack provisions. Hadoop, one of the most popular Big data frameworks, is entirely created in Java. 

So, if you’re keen on building Big data applications, then learning Java is the key.

14. Scientific Applications

Due to Java’s robustness and reliable security features, it is ideal for developing scientific applications that are fast, secure, highly portable, and maintainable. Java also provides powerful mathematical functionalities that produce the same result on various platforms.

MATLAB is a powerful scientific application that is coded with Java.

15. Amazon

Although Amazon is famous among people as an eCommerce store, concerning Java, you will discover it from a different angle. Amazon is also renowned for the development and delivery of cloud services.  

They use Java for its web services (AWS) and writing automation programs.
