Hi,
Regarding switched expressions, is this supposed to work?
public class Basic implements EntryPoint {
@Override
public void onModuleLoad() {
getKind(Kind.A);
}
private static String getKind(Kind kind) {
return switch (kind) {
case A -> "1";
case B -> "2";
case C -> "3";
case D -> "4";
case E -> "5";
case F -> "6";
case G -> "7";
case H -> "8";
case I -> "9";
case J -> "10";
case K -> "11";
case L -> "12";
case M -> "13";
case N -> "14";
case O -> "15";
};
}
}
Because I'm getting an error that says:
Compiling module it.pkg.Basic
Compiling 2 permutations
Compiling permutation 0...
