JAVA or Python for Raspberry Pi

Hey guys I am a java developer so it's easy for me to work around JAVA so i started like that and for every project. It's been around 2+ years i am onto JAVA only but I am just curious to know in performance wise which one is better as per your experiences...

Hello Bikash!

Consider that as you have a wider experience in java probably you will be more used to develop with this language than Python. The performances are better for Java when you need to manage the hardware, in my opinion, as it is nearest to the machine operating system than Python. By the other side, Python is not so fast by itself but almost all the features made available with this language are based on C/C++ libraries so the resulting hardware responsiveness and performances are anyway good.

I suggest you can start with the language you better know and - recommended - start playing on the Raspberry PI with Python as there is a wide number of libraries already available with this language. A more complex alternative can be what I am doing when I need a more direct software machine control: see the sources of the Python library and recompile the part you need (excluding the Python wrapper code) then integrate the hardware features in your Java application or port the parts you need from C to Java. But these last two ways are more complex, I think.

I happen to agree 100% with Enrico. I would also like to encourage you to always widen your resume with as many developer skills and proficiencies as possible, it is always a plus, you could only benefit from the experiences and knowledge acquired.

Hi Bikah,

anyway, if you base skill is better in java as you says, take in account that the PI already includes a full java support. Especially with Arduino and other micro controllers you can find good references supporting java libraries. And as java can work almost at the C++ level in the machne, it is not difficult you can include "as-is" Python components you find here and there for specific hardware interfacing.

I have not yet experimented - but maybe it is necessary soon - that the same C++ libraries used by Python (usually very well documented) can be interfaced with Java programs without great difficult.

oksbwn can do both using https://github.com/mrj0/jep . This code uses JNI which is safe even with heavy threading. Give it a a whirl (try it).

Hey clemm thanks for your feedback. Sorry i didn't mention that i am already using JAVA with Raspberry Pi.And for GPIO programming i am using Pi4J library.
