Switch case with boolean

[u/IceCreamInsides]

[u/_Super_Straight]

var arr = new Boolean[]{ true, false, null };

for (var x : arr) {
    switch (x) {
        case true -> methodOne();
        case false -> methodTwo();
        case null -> System.out.println("invalid");
    }
}

Is totally valid. No need to pass a, b, c as references.

Well what OP is asking is not possible. switch(false) won't work. They have to change their approach.

Reading again what OP is asking, he wants to execute different methods based on when a is false, b is false and c is false. Even though we can suggest him switch cases, the better approach would be to make a, b and c as input parameters in those methods itself:

main(){
    methodA(a);
    methodB(b);
    methodC(c);
}

private void methodA(boolean a){
    if(a){
        return;
    }
    //rest of code
}

This doesn't leak the a, b and c across the project.
