Its main competitive advantage lies in the fact that Java isn’t subjected to any hardware limitations. In other words, the language offers a high level of portability meaning that it’s possible to write and debug a code written in Java and deploy it to any computer that runs Java Virtual Machine. No wonder that lots of companies employ Java developers for their IoT projects.
This paradigm results in salaries. According to Payscale, a medium salary for Java developers in the US is about $88.000. It’s worth noting that these results don’t provide an exact image. When talking about paychecks, a developer’s experience and status are the points to rely on when calculating. For example, the gap in salaries between a junior and a senior Java developer in the USA may be around $30.000 (from $66.000 to $97.000 respectively). The geographical factor is also a point to consider. For instance, Java developers in California where the mecca of innovation and technology aka the Silicon Valley is located, get the highest salary nationwide –$133.000.
C is regarded a low-level programming language (however, it’s high-level enough to make programming simple), but that’s exactly what IoT development process demands. If to consider the fact that C allows a direct cooperation with hardware using a human-readable syntax, it’s a good match for many IoT-oriented companies. Besides, C is highly flexible and swift, and that’s good news for IoT systems with limited processing power.
These particular features make C a “second best” programming language for IoT development. Besides:
- C is a weapon of choice when it comes to constrained device development;
- C provides direct access to low-level hardware APIs;
- The language is available on almost every advanced embedded system platform;
When talking about salaries, again, the situation is different across the world. For instance, in the US, the average annual salary is around $100.000. Fun fact: according to Payscale, the yearly average C developer salary in the United Kingdom is only just over the $40 thousand. Do you have an idea why it is so?
Ironically enough, but just a few years ago, Python was considered as a language for developing web applications with no apparent application for IoT on the horizon. Nowadays, the situation has changed: Python is frequently mentioned as an easy programming language to understand and utilize in IoT projects. Some even claim that it is more flexible than C or Java, which have a lot of requirements and rules built up over the decades.
All in all, Python works as a charm for developing data-intensive applications, particularly if there’s a need to manage and organize volumes of complex data. Similar to Java, the source code written in Python is compact and highly readable due to the clean syntax of the language. Despite the fact that it’s not as fast as C or C+, you might consider Python if you work with small devices that have limited computational power and memory. Python is really popular for many SBCs (or Session Border Controllers) because of its convenience and the variety of simple libraries and Internet features.
As for Python-based salaries, in comparison with Java and C, they are a bit lower. An average paycheck is around $70.000 both in the United States and Europe.
