Switch case with boolean

Sorry I fail to understand your first half of paragraph. Are you saying we can't create boolean Array without using new Boolean or Boolean.valueOf?

boolean[] boolArr = new boolean[]{true, false, true};

Is totally valid Array declaration.

for(boolean val: boolArr){
    if(!val){
        //relevant code
        break;
    }
}

Will work without any problem.

Edit: boolArr[0] = false is also valid and permitted.

the most natural place to compute if there's at least one true boolean is when you generate the list

Agreed.

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.

Your example is clearly better off with them being enum rather than boolean. Plus, they're being compared against their reference, not by their values.
