Top 5 Most Used Applications Of Java In 2022

Technology is continuously going through development, and so are the languages used to develop them. One such well-liked programming language was created in 1995 and has a large number of commercial applications of Java today. A Java applet could formerly be seen on any website you visited; today, developers mostly use Java to create server-side, desktop,  and mobile applications.

The fact that three billion devices presently use Java for development is astonishing. This is due to Java’s incredible design, which includes the ability to run on any system. As a result, it has played a significant role in creating numerous Java-based applications and developing important technologies.

Because of its incredible features, Java has grown to be the most powerful programming language. Platform independence, Object orientation, fast performance,  support for automated garbage management, and several other features are only a few of its advantages.

Of course, this does not imply that Java is the ideal solution for all issues. On the contrary, although less popular for some applications of Java, it is a dominant choice for many. So, without further ado, let’s examine different Applications of Java, what Java does really well, and what Java could improve. But before that, let’s first understand what the applications of Java are.

What Are The Applications Of Java?

Java is a general-purpose, cross-platform language. It is well-known, widely used, and supported. Java is usually the first programming language developers learn because of its extensive history and vibrant community. When Java was originally released, programmers mostly utilized it to make embedded web applications.

Even though Java can seem complicated, with the appropriate trainer, it’s not difficult to learn. You can learn more about programming as well as its structures by studying Java through projects and tutorials. Just a few of the languages that Java has affected are Scala, Ruby, and C#. With Java, learning these and other programming languages will be simpler for you.

Top 5 Most Used Applications Of Java

Despite the arrival of numerous new and fancier languages and tools, Java is still one of the most widely used programming languages in use today. So let’s move on to the famous Java applications.

1. Java Desktop Applications

On your computer, desktop programs like Adobe Photoshop and Microsoft Word are installed. Although the majority of programs nowadays are cloud-based SaaS solutions, you presumably still download software suites like Slack from time to time.

In the past, C++ has been used to create desktop programs more frequently than Java. However, programmers frequently prefer Java due to its versatility, making it perfect for cross-platform Java-based applications. Unfortunately, Java contains some memory leaks and security vulnerabilities right out of the box. But it may be made to be quite secure and efficient with the right hands.

Desktop Java applications examples:

  • Web browsers.
  • Word processing suites.
  • Image editing applications.

2. Java Embedded Enterprise Systems Applications

Small independent computers, known as embedded systems, are used to run a single software or application. Routers, switches, and TVs may be a few of these. These include a lot of Android smartphones, especially older ones. On the other hand, vital services like medical equipment can even use embedded systems.

Many embedded systems today are internet of things (IoT) devices because they connect to the web and take on the characteristics of IoT devices. Java is a great language to use when creating embedded Java enterprise applications because of its portability. Furthermore, when properly programmed, Java provides direct access to numerous background processes, which enhances system performance.

Embedded Java applications examples:

  • Fitness trackers.
  • Medical devices, such as insulin trackers.
  • Smart TV.

3. Java Mobile Applications

The development of Android apps is currently one of Java’s best-known use cases. But the main reason is that other apps have begun to be eclipsed by mobile development. As a result, a lot of Java-proficient developers have shifted to developing for mobile devices.

For rapid deployment, new developers are more likely to utilize Python or a JavaScript framework, although newer does not always equal better. Nevertheless, due to its community’s strength and its environment’s richness, Java is still a top choice for creating mobile applications.

Java Mobile application examples include:

  • Mobile games.
  • Music and video and streaming.
  • Banking apps.

4. Java Big Data Cloud-based Applications

Java is a popular programming language for developing big data applications. For instance, Java is used to run Hadoop, the most widely used set of big data technologies. Moreover, the object-oriented design of Java makes it a strong choice for creating big data Cloud-based applications in addition to its portability. But if you use Java for big data projects, you could encounter certain performance problems.

As a beginning developer, you’ll hear conflicting opinions regarding Java’s performance and scalability. Although Java is a very scalable and high-performance programming language, it might be challenging for a novice programmer to write scalable code. The performance of a programmer’s code improves with expertise. For instance, effective memory management will lessen the possibility of memory leaks, but ineffective memory management might ruin a platform. Java provides almost total freedom, which has advantages and disadvantages.

Examples of big data applications of Java include:

  • NoSQL database management.
  • Document management.
  • Machine learning systems.

5. Java Web Applications

Although one application of Java is the web, which is typically used for server-side development, it is somewhat out of date. Java is a portable, flexible, and lightweight language. But it takes a while to write programs in this language.

Since developers prioritize getting their products to market as rapidly as possible, languages like Python deliver code considerably more quickly than Java. However, programmers continue to utilize Java for online applications, particularly when they want a quick, effective, and scalable language.

Examples of web applications of Java include:

  • Software-as-a-Service solutions.
  • News and Blogs websites.
  • Social media websites.


Every area of software development uses Java. There are still many more applications of Java to be investigated, including distributed applications, enterprise apps, IoT technology, and many more. Although many different programming languages exist, Java remains the preferred choice for most developers.
