Can there be multiple value assignments for the enhanced switch statement?

Allen Liao :

I'm trying to initialize two variables with an enhanced switch statement:

int num = //something

boolean val1;
String val2;

val1, val2 = switch(num) {
    case 0 -> (true, "zero!");
    case 1 -> (true, "one!");
    default -> (false, "unknown :/");
}

Is this possible?

ernest_k :

There's no tuple unpacking in Java. A quick alternative that still uses a switch expression could use a custom class (using Pair in the following example):

Pair<Boolean, String> val = switch (num) {
    case 0 -> Pair.of(true, "zero!");
    case 1 -> Pair.of(true, "one!");
    default -> Pair.of(false, "unknown :/");
};

boolean val1 = val.getLeft();
String val2 = val.getRight();
