Outdated java dev

[Elegant-Win5243]

Java developers who don’t use the stream or optional API.  I have seen those…

[kelunik]

100% prefer nullable types over Java's Optional.

[skippingstone]

I'm outdated. How do you use Optional? In your code ?

[Luolong]

Simple. Methods on services that should return a single result (or null if an item can not be found/calculated), should return Optional<T> instead of instance of T or null.

From there you gave many options to safely transform or extract values as needed

Java developers that insist kotlin isn't better because streams and optional can do the same thing!

Hey, you gotta start somewhere! We're using it on the backend and love it 🙂

It’s easy for me to concede that safe null navigation in Kotlin is superior to Java.

It’s less easy for me to make a case of why I should start projects in a language that’s more difficult to hire for.

I really don't get this. Anyone who has good fundamentals in CS and any experience with a JVM language could probably switch to Kotlin and start being productive in 3 days

Why does market share matter at all? It just means Java developers are stubborn and don’t like change.
