Pi4J V.2 Released!
The Pi4J Project was started in 2012 by Robert Savage, the same year the Raspberry Pi was introduced.
After long rework, the Pi4J library (a friendly object-oriented I/O API and implementation libraries for Java Programmers to access the full I/O capabilities of the Raspberry Pi platform) has taken a big step with the first release of the V.2.
Java in Education: Combining Java with Raspberry Pi and the Pi4J Library
Although a lot of universities and high schools focus on Python and C# in their program, there are luckily a lot of others who go “full Java”.
Don’t get me wrong, I definitely don’t want to start a “programming-languages-war”, but Java is the language I used myself more than any other for the last 10 years.
Setting up a new project or building a proof-of-concept for a new idea, is a matter of hours. And there is always a solution for the problem I need to solve.
This is probably true for each developer who has enough experience in the language used the most. But having used and experimented with many other languages, I still keep returning to my “one true love”, being Java, as it always delivers the result I’m aiming for, with the right amount of code to be readable, understandable, and testable!
