Please friends am new in programming and I need to know the types of programming departments please cos I don't where I belong.

Question

programming

Answer 1

My bad in assuming you meant Android apps, but dude, you posted about IoT which is dominated by Android, Ubuntu, and latecomer Windows. Of them Android had the biggest share.

I realise you mean stuff like JME (Java Micro Edition) like in feature phones or older boat equipment, but that 8 or 16 MiB memory requirement. And it's not Java the way C isn't C++.

I did not see anything on that thread you linked about Ada (which has been in moratorium for years), but even if I had, it's a Quora thread full of opinion. It's the internet, you shouldn't take things as gospel.

So I went to Oracle and looked through their systems. Turns out they do have an Embedded Java. So you're right there. But it's not quite the Java you make desktop apps in. If you'd said "Java Embedded", I'd not have thought you meant apps either.

However, C is still better for embedded programming than Java Embedded for the same reasons that it's better than C++: "pure code", smaller code, zero overhead/bloat, better understanding of what you're doing, etc. But it's a matter of choice.

Again, sorry I assumed you meant Android apps, it's a common thing around here.

Answer 2

thanks for understanding and no problem,no need to say sorry for minor confusion
and yes I agree with you that choosing a language to do a task is a matter of choice.

Answer 3

learn java and C , then proceed with what you are comfortable with.Both have their own advantages.Also get info about java micro edition .it is worth a try

Answer 4

Why do you want to learn?
For what ultimate goal?

Answer 5

I think if you want to write drivers write with C but for writing code for electronic appliances like microwave,modern fridges or any machine connected to the internet of things go with Java

Answer 6

all the mechanized goods like fridges microwave etc that can't connect to internet use java code in some form or other

you may prefer c but java has worked fine till date

Answer 7

the main purpose of inventing java was to make white goods computerised
these white goods include all kinds of microwaves,new fridges,
basically anything that has buttons and electronic circuits and not limited to smart devices
Kindly read till the end of online article which mentions that Java and ada are quite suitable for embedded systems in electronic hardware (even non smart devices) and have powerful tools and lots of potential if properly used
This is what I meant and I never talked about Android apps to control those smart devices.
Google java processors and you will be presented info about chips that are build from ground up to run java in embedded chips.Since they are specialized they can run java with minimal resources.I am not saying embedded systems in electronics only run on java but they are easier to program with Java which is built keeping simple coding in mind.

Answer 8

Divyansh Dabral I think you're misunderstanding this thread. JVM would not fit on an SoC whose total memory was a few hundred KiB to a few MiB, let alone run. What you're talking about is making Android applications for smart devices. What we're talking is tiny hardware components that are part of something that may or may not be a "smart device".

Answer 9

writing programs for hardwares

Answer 10

Okay, for hardware, you'll deal with C and possibly some assembler code as you'll find yourself writing very tiny codes for microcontrollers.

If you meant "for hardware" as is drivers, you're also looking at C.

A career in hardware engineering, programming, and design can be interesting and lucrative in today's digital world.

Answer 11

What about C++?

Answer 12

Some hardware uses C++-written code, but most prefer C because a C compiler is very easy to write and C can be more optimised when dealing with very, very limited resources. C++ has abstraction upon abstraction. It can produce bulky code post-compilation. It's a language focused on design, whereas C is closer to the core and allows many speed hacks.

The majority will be in C/ASM for MCUs, but if you wrote firmware for, say a larger-scale SBC with higher specs or more complex functionality, C++ would be an option. However you'd probably choose C by then because you were comfortable with it.

Answer 13

That means that I can build any electronic devices with Java? but if it is, how can I get started with it...

Answer 14

Thanks you guys 👍, I really appreciate you guys...

Answer 15

for what aims u wanna learn?
