need some form of DI using reflection too
Try increasing the line count to at least 6000, twice for good measure, and another twice in a different framework for quick design proposals. Of course with a giant Wiki documenting the steps to set up the Kubernetes to manage the Docker instances on the cloud servers.
@CTimmerman ahaha
Sufficiently advanced Java is indistinguishable from satire.
Everything is in the same file? Ew! Here's a proper Enterprise edition: https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpriseEdition
Code is not structured!
One of the customers is complaining that the letter o in Hello World is too similar to the digit 0 and it is giving him a headache. You have until tomorrow morning to solve it.
It needs some externalized configurations and definitely a IoC/DI engine.
Where is the CI/CD pipeline?
yes
Line 71, among others, exceeds 80 characters. This is terrible for legacy reasons. CPU cycles to wrap lines aren't free, and neither is training to enable that.
Sheesh. If you're happy with code that doesn't abstract StringFactory
into an interface then please feel free to send this to production as is. But my product manager is gonna go insane if we want to swap it out for another kind of string factory for reasons. I heard that GoodbyeWorld()
is in the offing for quarter 3 and we're going to want to reuse as much of the existing codebase as possible so maybe you might want to think about that?
no scalability
why are there no comments?? why is the formatting so weird? also this is obviously performance critical code that should be written in assembly! also how do you expect a 200 line program to run and ship on hundreds of platforms? literally unusable!
No i18n support???
hahaha sorry
Lol in terms of “enterprise good practice” for local variables in functions/methods that are not meant to be reassigned you should be using the “final” keyword. Same for function/method Paramus that are not meant to be reassigned, use the “final” keyword.
Otherwise the checkstyle PRB might get made at you :p
Also does this repo have required checkstyle PRB, spotbugs PRB, and unit test with jacoco code coversge enforcement PRB required to pass to allow merges along with at least one approval by someone else? If not tsk tsk…
(btw I know this is a funny joke repo on enterprise app over-engineering but I’m just playing along).
lgtm
Now, what if the format of the output is not structured? do we need an LLM and StructuredOutputParser? then make sure to deploy it on the Edge!
Unfortunately this is not event driven. Please refactor. 😉
Lol. There is a code smell that
IHelloWorldString
andIPrintStrategy
are extracted fromhelloworld
and then you put them back to print! Clients are doing something they don't have to for you! YOU SHALL REFACTOR those three lines into one! XD
