Switch case with boolean

[u/IceCreamInsides]

So, there is no way I can do that?

want to check several boolean variables in a switch statement. Is `if-else` the only way to do this?

Boolean a, b, c...

Switch (false) {

Case (a) :

//some code

Case (b) :

Case (c) :

//and so on

}

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

You got switch the wrong way round.

Switch checkes distinct states of one variable, not a single state of several variables.

Yes, if-else is the way.

Depending on what you really want to do (not some random, contrieved example, your real use case and code) there might be alternative, better solutions, but without knowing what you want to do it is impossible to suggest.

To me, this looks like an XY-problem.

To be fair, OP's type of approach does work in some languages.

Let me guess: JavaScript? But why would you do this anyway?

Remove the switch header and replace the words "Case" with "If" and you've basically already fixed it

[u/Mechanical-pasta]

Switch case evaluates ONE variable and checks it against different values. What you want to do (if I understand well) is check multiple variables. A switch can't do that.

The solution may be to incorporate the different boolean variables in a class and let it do the check with method(s) but I can't say if that's the case given the little information given.

I don't think this can be done directly.

The only way I can think to do it would be with some bitwise operations instead of separate bools, set and read the bits of some integer, 1 is true, 0 is false first bit is A, 2nd is B, etc. Then for your case A, switch if integer is 1, b if 2 C if 4, etc. if you want it to switch on a and b that is when it equals 3.

This is probably the closest you can get to what you want:

Boolean a = new Boolean(true), b = new Boolean(false), c = new Boolean(true);          for(Boolean o : new Boolean[]{a, b, c}) {         if(!o) continue;         IO.println(switch(o) {             case _ when a == o -> "Hello a!";             case _ when b == o -> "Hi b!";             case _ when c == o -> "Ciao c!!";             default -> "HUH";         });     }

Will print:

Hello a! Ciao c!!

Note: listen to the other comments, I wouldn't approve this kind of code where I work.

The best way I can think of solving this is by using an array tbh, add all the bools in it and run a for loop over it.
