Embracing The World Of Java And Internet Of Things: Useful 3 Step Guide For Beginners


Java and the Internet of Things are a predestined perfect match – Why? Because since its inception, Java has been a strong backbone for many emergent technologies, and IoT is not an exception.

If you’re a beginner who is considering to make your career in the revolutionary field of IoT, there can be many unanswered questions such as:

What is the rage about implementing Java and the Internet of Things, when there are so many other programming languages available in the market?

  1. Do Java and the Internet of Things work better together?
  2. What is the importance of Java to the Internet of Things?
  3. Why is Java IoT a perfect combination?

Worry not, this blog intends to answer all these questions and explain why Java and the Internet of Things are the best bet for each other.

According to many studies, Java offers various advantages, thus, makes for an excellent choice for IoT. One such benefit is that unlike other languages, Java allows you to write the code once, and then use it and run everywhere. The Eclipse Foundation has surveyed IoT developers globally since 2015 to understand the ecosystem, trends, and challenges in the field. According to the 2018 survey, IoT using Java topped the charts with a whopping 66.5%, making it the most popular programming language for IoT development. 

1. Do Java and the Internet of Things work better together?

The answer is yes; both Java and IoT are inseparable.

IoT is a revolutionary technology that has taken the world by storm. After the internet, IoT is the most sought-after invention. The IoT market is growing by leaps and bounds, as there are so many new computers, devices, and technologies everywhere. According to IDC, by 2021, the total number of IoT devices worldwide will cross 35 billion. More businesses are investing heavily in these initiatives, and hence, the demand for IoT developers has increased exponentially. 

Every market or industry vertical has abundant opportunities for using IoT with Java because of its flexibility. Java is easy to write and use, compile, learn, and debug. This programming language is designed to connect things. Interoperability or coordinated working of various and multiple devices is a characteristic trait of the Internet of Things, and Java bids just that. 

2. What is the importance of Java to the Internet of Things?

Java is relatively less complicated and easy to use as compared to other languages, making it a preferred choice for developers. It also eliminates security problems for data, which makes it suitable for the internet. There are many explanations for choosing Java as a preferred choice for IoT developers, let us go through a few of the attributes that make the development of IoT using Java achievable:

A) Platform Independency

While developing an embedded application, you need to consider the real-time OS, processor, and different protocols to connect devices. The fact that a platform-independent language like Java summarises all these factors, helps developers to write the code once and run it anywhere. The developed Java IoT application can run on different hardware devices and platforms without changing the code. It makes the deployment of IoT with Java more efficient and less cumbersome.

B) Flexibility and Easy Migration

Flexibility and universal virtual availability of Java make it the best platform for the Internet of Things. Java IoT applications are easy to migrate to a newer platform, which reduces the chances or error and issues.

C) Minimal Resource Consumption

Java has been developed to run in resource-constrained environments. Therefore, the development of IoT with Java will utilize minimum resources and deliver maximum efficiency. 

D) Extensive APIs

Internet and Java programming offers its users the benefit of more than 4,000 libraries, encompassing all the IoT programming requirements ranging from concurrency to networking. API requires minimal or no rewriting, which leads to quicker code execution and IoT app development. 

E) Robust Code

Implicit pointers are used in Java that cannot be manipulated because of the robust application code. There will be fewer possibilities of problems like memory access violation and buffer overrun, hence highlighting the importance of Java to the Internet of Things.

F) Easy Accessibility 

Java is easier to learn than most of the other programming languages. It offers multiple functionalities like security and scalability, making Java and the Internet of Things a good fit.

G) Networking

Embedded systems need to be aggregated and analyzed from various endpoints to convert them into useful data called data centers. These data centers can be developed into an efficient and accessible system with Java and the Internet of Things.

3. Why is Java IoT a perfect combination?

Java offers ubiquitous connectivity power and constantly evolving capacity, making it the most preferred programming language for IoT devices and systems. 

  • Java-powered IoT devices are more effective in exchanging and retrieving information. Using Java makes IoT devices more integrated.
  • Java has the ability of automatic up-gradation, which makes it cost-effective and an excellent choice for IoT systems.
  • Java re-uses the modules through various domains and has a fantastic market reach of millions of developers and end-users across the globe.
  • Java is portable, supported by different hardware, and offers secure connectivity, thus, making it more preferable for IoT systems.


IoT is based on embedded technology, Big Data Analytics, and Artificial Intelligence. Implementation of IoT requires many considerations, as it deals with many data streams, and that’s where Java comes to rescue.

The universality, versatility, flexibility, and reliability of Java allow it to adapt to IoT application development with minimum resources and efforts. It is the best time to explore the real potential of Java and the Internet of Things because IoT using Java is the future! Learn relevant programming skills and emergent technologies to reshape your career landscape through our Master Certificate in Full Stack Development program!
