Every day, there are more devices everywhere connected to the Internet, waiting patiently for our commands. How can we order them around? Which language do they speak? The simple answer is that these smart things use many of the same languages as desktops, in part because their similarities with desktop computers continue to grow.
In a survey of developers who write code for the Internet of Things (IoT) conducted in April 2016, the Eclipse Foundation discovered that Java is the top choice for developers who are “building IoT solutions.” It is a result that’s not surprising for a language still known for being “write once, run anywhere.” The original project was aimed at set-top boxes, one of the first domains for non-desktop computing.
Well Known Advantages
Java’s advantages are well known. Developers can create and debug code on their desktop and then move it to any chip with a Java Virtual Machine. That means the code can run not just on places where JVMs are common (servers and smartphones), but also on the smallest machines.
Java ME, or micro edition, has been available on small phone handsets and other embedded devices since the specification was approved in 2000. It saved space with a very limited collection of class libraries and other tools. Today, most of the focus is on Java SE Embedded, which is much closer in capability to the Standard Edition. Developers can use the latest features of the Java 8 platform and then move their code to a smaller, embedded device.
Embedded Apps with Java
According to a report by Oracle, one of Java’s biggest perks is the robustness of application code. While C uses explicit pointers to reference memory, all object references in Java are implicit pointers which cannot be manipulated by application code. This automatically rules out potential issues such as memory access violations that can inevitably cause an application to stop all of a sudden.
Most of the computing resource savings with Java SE Embedded comes from stripping out the classes needed to display information when the machines can be configured to run headlessly, without a monitor or keyboard. All of the communication goes through the network.
While migrating applications written in C to a new platform could be both costly and time-consuming, as well as error-prone, another advantage of Java is that it runs anywhere after it’s been written once. If the APIs used by the application remains unchanged, it is just a matter of redeploying the existing class or JAR files. A simple recompile will be enough if you want to move to a newer version of Java.
Thus, portability and fine hardware control make Java as the supreme choice for IoT programming. Java code is paying back decently on a number of platforms are supporting it. Moreover, Java taught as a primary programming language in all tech courses that makes easy availability of Java programmers among the developer communities. Google has supported Java by introducing Android language with obvious support of Java and its libraries in mobile application programming.
Internet of Everything with Java
Almost all devices, from personal computers to mobile phones, uses Java. It is also an integral part of the internet world, making it a great choice for IoT. Java provides every device the best functionality level, high-security levels and a good amount of scalability in the industry. Moreover, the fact that Java has a big ecosystem makes it much more suitable for the internet of everything. Senior Java developers can create innovative apps to help achieve the goal of a connected world.
