What technologies are used in touch-screen Keurig coffee machines?

Question

That broad question breaks down to a couple more specific ones:
1. Is Java technology used in some Keurig coffee machines?
2. What other technologies are used for graphical interfaces in coffee machines?

I know that Java technologies have been used in Blackberry phones, bank machines, and a variety of other devices but had trouble finding it clearly mentioned for Keurig coffee machines.

To be super specific, I'm curious about this particular machine that is used at my workplace:

I found a very similar question at https://www.reddit.com/r/Showerthoughts/comments/3s5gu8/is_the_keurig_coffee_makers_computer_programmed/ but it isn't clearly answered. Responses debate c++ or Java.

Answer 1

Josh Greig really good question, can't wait for the answers

Answer 2

If the code isn't open source, they haven't said what language its in, or theres no api then you cant know

Answer 3

For this type of question, I would use Google. I think the chance of Sololearners knowing the specific technology used in a particular brand is low.

Answer 4

Sonic, I already searched on Google. That's how I found https://www.reddit.com/r/Showerthoughts/comments/3s5gu8/is_the_keurig_coffee_makers_computer_programmed/ It would have been lazy of me to not search for an answer before asking the question. I didn't find a clear answer yet, though.

Answer 5

Ole113 I was hoping someone who did engineering work for Keurig or other embedded systems would have a fairly confident answer. I'm guessing it is Java based on how sluggish the UI is, how the input controls look, and the wide variety of devices that run Java.

I asked my employer's coffee machine repair technician but he wasn't sure.

I found this related job posting from Keurig which points to c++ but Keurig is a huge company and might be hiring developers to work on software that isn't part of their machines:
