For years, Java has been distinguished by its wide and frequent usage, as shown in numerous rankings and a community of more than 9 million developers. And there are a lot of software companies in the market that have other own Java development departments. On the 2022 PYPL index, Java ended the year in second place; on the TIOBE index, it’s in the Top 5. Despite its long tenure in the market, it is still a highly desired and needed programming language. And it continues to evolve as it’s utilized for various technical solutions in multiple industries.

Java is good for cloud, Big Data, AI, IoT, and Omni

channel solutions due to their versatility, adaptability, and reliability. Using Java, it’s possible to both create advanced software products from scratch and upgrade or rebuild legacy systems. This language perfectly fits diverse architectural approaches: microservices, API development, SOA, and monolithic applications. Java has a powerful development environment and provides a lot of functionality to meet each project’s specific needs.

So why choose Java for your project? Here are some major advantages:

  • Multi-threading, which means each thread runs independently and does not affect others. This feature makes Java a correct choice for building high-load systems with great performance. Such systems can simultaneously carry out many calculations and handle many data requests.
  • Portability enables Java code to run in multiple environments due to its platform-independent feature. It meets the so-called “write once, run anywhere” principle. You may write or extend your code just once and deploy it, when necessary, on any platform, including Windows, Mac OS, and Linux.
  • Its open-source feature decreases the risk that the code owner will cease to support it. With Java, you can build standard components, reuse code, expand and support existing systems, and easily debug complex systems.
  • Versatility and stability. Java has a wide range of use cases, from simple applications to large-scale enterprise software. All software solutions can be tailored to specific business needs. It also unlocks the entire potential of cross-platform and cloud development.
  • Compatibility. Java can be combined efficiently with other programming languages in one app, such as Scala, Kotlin, Groovy, and Clojure. For example, Java and Kotlin can be used together for Android mobile development, and code can be converted from one to the other in both directions.

Industries that can benefit from using Java

Based on what was stated above, the Java language is a practical and powerful choice for many industries, for both Enterprise Resource Planning and Business Intelligence systems and consumer apps. Besides computers and smartphones, Java-based apps run on a great many devices, such as medical instruments, ATMs, various types of terminals, parking meters, and game consoles.


Java allows you to build reliable and powerful e-commerce platforms with a smooth, attractive interface and can be integrated with most third-party APIs. This offers a coherent user experience over multiple channels, with high speed and fewer hangs or user timeouts. An e-commerce platform developed in Java is capable of processing large volumes of orders and real-time data for more efficient decision-making.

Examples of e-commerce businesses: Amazon, Rakuten, and eBay.


Java can empower various businesses in the financial industry with secure, flexible, robust, and reliable software products. Finance-related software includes a broad spectrum of applications: digital finance solutions, data management and client management dashboards, exchanging platforms, repayment and collection frameworks, embedded telematics solutions, information handling frameworks, and many others. Java server-side applications generally provide fast and consistent data exchange between the client and the server, creating settlement and confirmation systems, data processing, and so on. Also, for example, by combining Java-based pattern matching with natural language processing and machine learning, one can develop a fraud-detection algorithm.

Examples of financial institutions: Revolut, JPMorgan Chase Bank, and Citigroup.


Java has strong potential in healthcare software development. One can use it to develop diagnostic and interventional systems, wearable and embedded device applications, BI solutions, and all-in-one e-health care management systems. Healthcare software use cases involve document flow management, tracking disease dynamics, patient management, invoicing, and more. A more consumer-related part of healthcare software development is mHealth apps. This includes a variety of applications dedicated to lifestyle management and fitness, nutrition and diet, women’s and men’s health, medical consultations, and much more.

Examples of healthcare solutions: Cardinal Health, Samsung Healthcare, and CVS Health.


Automobile manufacturers are looking to solve a variety of challenges for passengers and drivers through digitalization, such as control and safety, entertainment, and other digital opportunities. Automotive systems developed with Java can run many functions in modern cars — for example, cloud services, embedded controllers, and various types of in-vehicle software. The software must be able to store and process large volumes of data. The cloud, car peripherals, sensors, roadside equipment, and mobile devices form a unified network exchanging data.

Examples of automotive companies: Mercedes, Mazda, Toyota, and Titan.


Java is applicable to a large variety of use cases in the retail industry, from all types of everyday operational activities to attractive websites and web apps. Examples include robust and large-scale management systems for warehouse inventory control and transport of goods, customer data management, and shelf management. Java can be combined with AI and computer vision algorithms to create new, engaging customer in-store experiences through personalized service, automated payments, and in-store advertising.

Examples of retailers: Costco Wholesale and Target Corporation.


In 2023, Java will be 28 years old, and its future looks promising. The language has maintained its top ranking among favored and widely used programming languages. A lot of companies, including those in the Fortune 500, and developers choose it for web and mobile development, API development, cloud-based and cross-platform solutions, and legacy code modernization.

Java is hailed as a robust tool for large-scale enterprise solutions, but startups also can benefit. Startups can count on its reliable and stable performance, a huge number of tools for data processing and analytics, and built-in support for Android mobile development. Among recognized startups that have chosen Java are Grammarly, SmartThings, BlaBlaCar, and

Choosing a tech stack and architectural approach that will best fit your project is a crucial task, alongside finding a reliable partner. When selecting a Java development company, make sure they understand all of your requirements, can suggest the best development model and use a modern Java stack.
