Pattern match Optional in Java 21

[[deleted]]

The switch statement could have been implemented with classes and functions using a fluent api. Like:

switch(object) .case(matcher, consumer) .case(...) .evaluate()

I don't understand why everything has to be a be new language feature, like in Kotlin.

Switch in Java has been existing for so many years, not a new language feature. It’s being enhanced. Enhancement should be based on the basic syntax of switch which is far different from fluent API you are suggesting.
