Amazing info. Long awaited. Thanks a ton for taking the initiative.
After Oracle took Java along with sun a lot of confusion followed with various version numbers.
Perhaps now they can plan migration to higher levels ..

Double getArea() {
return switch(this) {
case Circle2(Double r) -> Math.PI * Math.pow(r, 2);
case Squar2(Double l) -> l * l;
default -> throw new IllegalArgumentException("Unexpected value: " + this);
};
}
when I try to do the same I get the following error: Cannot switch on a value of type Shape. Only convertible int values, strings or enum variables are permitted
in the return switch parameter.
I am using Java 17. LTS

56:10 you can, with --add-opens, but you shouldn't
While I said that, the problem is that some API don't have the choice and the JDK doesn't offer a proper way to help them.

[@FrankConnolly8]

I wonder if he wants me to update from Java 8... he's not very clear on this

[@USONOFAV]

Newbie java developers won't understand the fun in coding with newer versions of Java until they have coded Java1.5 and below.

[@paulfrischknecht3999]

I don't think I would care when choosing a job which version of Java is used there. Never asked that question.
