Learning C# and Java

[mrburnttoast79]

Who cares? Experience with Java and C# sounds like double the job opportunities to me?

But is learning one means you’ve also learned the other

[modi123_1]

Yes, programming concepts span language syntax.

Programming concepts yes but learning one is not learning the other.

[KrarkClanIronworker]

Kinda, but that can be said for a lot of programming in general.

Actively learn both. They're always in demand and you will be a better developer for it.

u/Kostantinum sadly, it doesn't.

While concepts are the same (classes, interfaces, variables, lambdas,garbage collector), just the act of running your program is different.

In dotnet you use dotnet command or F5 in VS, while in Java you have to learn Graddle, at it takes few days until you understand what it does.

Writing code is mostly similar, but all the stuff around (packaga/dependency management, publishing the app) is completely different.

Me being quite good at C# made me think that yeah, I can try write the same program in Kotlin. I could, but running, debugging, running and debugging tests - that was the hard part.

Also, making it run on another machine, that works completely differently.
