How Java Language Is Best for IoT Systems Development

Java is one of the most used languages in the world and the most successful language in the field of IT. This programming language owes its runaway success to WORA (write once, run anywhere), an important feature that removes the platform dependencies during application execution.

In older days, Java was easy to understand, write, compile, learn, and debug, which allows you to design modular programs and reusable resources. 

However, Java lost its popularity with the rising of other advanced programming languages. But this object-oriented programming language has surprisingly regained its popularity with the growth of the Internet of Things (IoT).

It's surprising that GitHub rated Java as one of the best and most popular programming languages in 2019. This programming language has gained respect for being the backbone for many technologies.

A survey of IoT programming at Eclipse foundation shared the same thing; that Java has 52% more respondent rating than Python, C, and C++ as the choice of programming languages and using for IoT system Development.

So, here I discuss the returning of Java from its grave and how IoT has played an important role in its return.

What Is the Internet of Things (IoT)

Internet of Things is the idea of connecting devices to the internet and to other connected devices in some way. The Internet of Things is a huge network of connected people, computing devices, objects, machines, and among other things.

All these things have their own unique identifiers (UIDs) and possess the ability to collect and share information over different networks without the necessity of human to a computer or human to human interaction.

The Internet of Things has gained massive popularity with the growth of data analytics and BI, AI, and machine learning.

From fitness devices to kitchen appliances such as microwave ovens, from self-driving cars to self-working robots, there is a presence of IoT everywhere.

How Java Is so Useful in IoT System Development

As written above, IoT devices share and collect information over different touchpoints. These touchpoints are created with an embedded application that is used as greater connectivity.

One of the best reasons for Java's popularity is that it is highly flexible and reliable and can be accessed from anywhere. The internet of things is not a single technology; it's a combination of technologies, including big data, cloud computing, M2M collaboration, sensor, computing, and hardware devices, making Java the best choice to bring all devices together.

Another important factor that makes Java application programming so useful in IoT programs that it contains a huge library of application process interfaces (APIs). It is the best feature is that you can use the existing APIs rather than creating new codes from scratch during the creation of embedded applications.

In addition to Java, an application created in Java faces fewer problems during application updation. Moreover, In the 90s, Java started writing applications for PDA, which were themselves embedded devices.

We can say that Java was born in an embedded environment. At the time, the computational power available was different than what it is today.

Benefits of Java in IoT System Development

Following are the benefits offered by Java that make it the programming language best for IoT applications development:

1. Java offers a real-time response to the endpoint devices, easier implementation, and J-shell.
2. Java offers more than 4000 libraries, which are used for faster code implementation and faster IoT application development.
3. Java uses implicit pointers, which prevent problems like memory access violations and buffer overflow. Robust coding structure makes Java more popular.
4. Java works on a minimum of resources as it was designed to run in a resource-constrained environment. 
5. Java Virtual Machine offers automated memory management, which allows developers to focus on writing codes rather than worrying about running them.
