How is Java a Good Choice for IoT Development?

Combining artificial intelligence or AI with embedded technology, the world is getting revolutionized by the Internet of Things or simply known as IoT. IoT is the next big thing going to storm the world by actively infiltrating our daily lives.

IoT is a new form of technology which enables machines to do human-like performances by connecting technology with devices in its ecosystem and communicating with them. It simply means; an interconnected network of physical devices, vehicles, buildings, and other items embedded with sensors, software, and connectivity which enables these objects to collect and exchange data.

IoT has stepped into a variety of things now; from smartphones to health gear, from smart homes to smart TV or refrigerator etc.

How does IoT Work?

IoT systems typically consist of three main components: IoT devices, communication protocols, and a central system.

IoT Devices

These are the physical objects that are embedded with sensors, software, and connectivity that allow them to collect and exchange data.

Communication Protocols

Some standards and technologies are allowing IoT devices to communicate with each other and with central systems. Some communication protocols used in IoT are; Bluetooth, Zigbee, and MQTT.

Central system

This is typically a cloud-based system that receives and processes data from IoT devices. It can also send commands and instructions back to the devices.

The Process of IoT Works as Follows

  • IoT devices collect data from the environment using sensors and other hardware.

  • The devices then send this data to a central system using a communication protocol.

  • The central system receives the data and performs analytics on it, such as identifying patterns or anomalies.

  • Based on the analysis, the central system can send commands or instructions back to the devices, which can then act.

  • The whole process continues in a loop, with devices constantly collecting and transmitting data, and the central system analysing and responding to that data.

Why is Java Highly Used in IoT?

The key to successful IoT lies in flexibility, and Java is well suited for this. Java and IoT together are made for each other for various reasons such as −

Platform independence − Java code can run on various devices and operating systems, making it a suitable choice for IoT devices that have limited resources and varying hardware. While developing any IoT system, one has to consider the facts;

  • Processor

  • The real-time operating system

  • Different protocols which will be used to connect the devices

Three of these factors come sorted with Java ME, so the developed IoT application is able to run over diverse devices without need of change of code.


Java has built-in security features that can help protect IoT devices from malicious attacks, such as encryption and secure socket layer (SSL) support.

Large ecosystem

Java has a large ecosystem of libraries and frameworks that can be used for IoT development, including the Java Embedded SE for small devices, and Java ME for resource-constrained devices. This provides developers with a wide range of tools and libraries to choose from, increasing the efficiency and speed of development.

Good performance

Java is known for its good performance, which is important for IoT devices that may have limited resources and need to perform multiple tasks simultaneously.


Java is a highly scalable programming language that can handle large amounts of data, which is important for IoT systems that process and transmit large amounts of data.


Java has built-in concurrency support which makes it well-suited for IoT development where devices are connected and must communicate with each other constantly.


Another prime reason for teaming up Java and IoT is the portability facility, with java Portability over the network works flawlessly. No matter whether you are using a desktop computer or smartphone, the system runs smoothly across all devices.

Advantages of Java in IoT Development

  • The devices are able to exchange data more effectively and use it when and where it is needed thanks to Java Embedded.

  • In order to implement code more quickly and develop IoT applications more quickly, Java provides more than 4000 libraries.

  • Due to its design for environments with limited resources, Java uses the least number of resources possible.

  • Programmers may concentrate on developing code rather than worrying about running it thanks to Java Virtual Machine's automatic memory management.

  • You must consider the real-time OS, CPU, and different device connection protocols while developing an embedded application. All these elements come together in a platform-independent language like Java, which aids programmers in writing code once and running it on any platform (WORA)principle.

  • Programming language Java is widely used. More people can access it, and it has a wider global market. Applications for the internet of things are quickly going viral.

Bottom Line

  • Using Java as IoT standard application language have many benefits such as;

  • Availability of a strong community with millions of developers around the world

  • Enhanced Device Performance

  • Higher product lifecycle due to self-upgradation facility with Java

  • Due to auto-update feature support cost gets reduced

In short, Java gives impeccable versatility, universality, and reliability due to which it’s the primary language chosen for IoT applications.
