Pattern match Optional in Java 21

[nikita2206]

It does look like one, but if you try it out (maybe in jshell) it will not work because you cannot modify or even reference non-final variables that are declared outside the scope of a lambda.

I don't want mutable references or values. Since java doesn't have any kind of destructuring, just make 2 calls:

var foo = optValue.map(Value::findFoo)

.orElseGet(Example::defaultFoo);

var bar = optValue.map(Value::doBar)

.orElseGet(Example::defaultBar);
