I’m learning swift and I actually just discovered ?? today. Am I missing out in other languages?

[–] qaz@lemmy.world 17 points 11 months ago

C# and Kotlin both have it

Yes, it's very useful when applied correctly.

I'm always disappointed when I remember, that I can't use such a feature, because I'm stuck using Java.

Maybe you'r using an older version of Java? Works fine for me.

New versions of java have a null coalescing operator?

I didn't know that.

Edit: a short search didn't return any answers, as far as I can see java doesn't have this operator, the closest thing is the ternary if operator.
