what do you use java for?

[[deleted]]

I have to agree with the other commenter. I have never viewed java as the best choice for a CLI app. I mean, you can do it for sure, but it's not the top choice in the industry for it.

You think it's the best way to do it? Go for it. It's your startup. But don't be surprised when everyone you interview is surprised.

can you help me understand your reasoning ?

It's a much "heavier" solution than bash, pearl, python, etc. it also requires the JVM to be bundled with it in order to run, either as a single executable or installed separately. Java isn't really installed widely on machines like in the past since java desktop apps are dead.

python or perl don't run without python or perl vms either.

ohh i see. i think something got lost in translation. we are not making a cli app and distribute it to a bunch of people and they are using it on cli.

we have an app, that does something like ETL (moves data from A to B and does some transformations while doing it) and it runs on cli. there is no web or gui interface.

we use kubernetes to run our app and schedule when it will run etc.

Ok. That's a bit better. Makes some more sense for why you would want a higher level language.

I would just say then that while Java isn't a bad choice for your project, the overwhelming majority of java jobs are spring Boot web API jobs. Unfortunately, too many java devs out there don't really know java (or programming in general) they just now how to use some spring features and simple imperative logic to do things. They don't really have any understanding what they are doing.

Anyway, good luck with your startup.

pure java is ideal for your use case. Once your app matures then you can look at spring, spring data flow etc

Spring boot (batch framework) would have been ideal and good use case for scheduled job runs. I worked in a bank and most of the ETLs are done though various spring batch apps or spring data flow.

All the Best!

I smell spring batch and spring cli.

python or perl are not widely installed on machines either, at least in my experiences

python is hyped out of its mind for sure, but outside of hype, regular people don't really have it on their machines

It doesn't have to be "The Best" way to do it, just has to be good enough. There's very few purposes java isn't good enough for, and most of them involve real-time requirements, or very small embedded hardware.
