One of the most popular Java developed Scientific tools is MatLab.

3# Java-based Enterprise Apps

Java programming language remains the first choice for developing enterprise software/apps. It is because of its robust features that deliver high performance. Other than the performance factor, Java also helps in building secure, powerful, and easy-to-scale apps, so developers prefer to use Java for enterprise app development.

It has a version called Java EE (Java Enterprise Edition) that has an API along with a runtime environment that helps in easy scripting and execution of the enterprise software, web services, and network tools.

As per the report of Oracle, there are almost 97% of enterprise computers that run on Java language. This could be the result of Java providing high-performance features and speedier computing services.

Other than that, Java also helps in developing small-scale apps as well. No matter how small or big an app or project is, some functionalities remain common. As Java is constantly updating to fulfill business demands, here are some features of Java that make it a better alternative for small or big software development:

  • Cross-platform compatibility
  • Flexible integration
  • Strong performance in managing large-scale workloads and even small-scale apps.

These are some of the amazing features that make Java a most suited alternative for enterprise project development.

4# Uses of Java- One of the uses is to develop Embedded Systems Development

Embedded systems are the combination of smaller units that combine to make a collective function for bigger systems. Java language has become one of the best solutions to help with managing software complexity.

Today a huge number of developers may use Java language in embedded systems. Also, Java has a huge variety of libraries for simplifying the developer’s lives.

These libraries can be simply reused by the embedded apps which increases productivity to a greater extent. Moreover, the presence of OOP makes it simpler to develop embedded systems even with less experience. All such Java features make it simpler for developers to maintain any complex system.

These systems are low-level projects that form a small but important part of a larger system. It can be a processor, a tiny chip, or any such thing.

Java has robust tools to handle such apps. Here are some of the best examples of Embedded systems developed using Java:

  • Blu-ray disc
  • SIM cards made using Java

5# Cloud Apps made using Java

Cloud computing refers to an on-demand access of computer resources without requiring a user for direct management. The Java language has carved a path in the development of cloud apps. It provides an affordable solution for IT infrastructure. Mostly, it serves as a platform for making cloud servers and apps.

Often Java is referred to as WORA- Write Once and Run Anywhere language. This feature makes it perfect to decentralize the cloud-based apps. Cloud providers frequently use Java to run their programs on different ranges of platforms.

6# Java used for developing Big Data projects

Big data is a popular and trending topic in the modern software development industry today. Big data can deal with systematically analyzing and extracting data from huge data sets.

One open framework that is popularly associated with Big data is Hadoop which is completely written using Java language. With functions like easy memory distribution, automatic garbage collection, and stack provision projects. Java also provides an edge over other technologies.

We can easily say that the Java language is the future of the latest Big data.

Here are some real-time Java-based big data technologies:

  • Apache HBase
  • Hadoop
  • ElasticSearch
  • Accumulo, and many more
