Java switch statements

Question

Was just wondering if I could do something like this in java with switch statements?

switch(a && b){

case 1:

//

case 2:

//

}

so as per your username, when I say 'Don't try it yourself', you really won't try it. — Prasad Kharkar

What are a and b and why would you expect && to produce either 1 or 2 when this operator returns a boolean? — Tunaki

Sure you can, but not with logical AND (&&). You probably meant to use bit-wise AND (as your case clauses suggest) :

switch(a & b) {
case 1: 
case 2:   
}

What is the data type of a & b ? If it is boolean then it won't work, switch works with int. If they are int then you must use single & operation and not a &&

 public static void main(String[] args) {
    int a,b;
    a=5;
    b=2;
    switch(a & b){

    case 1:

    //

    case 2:

    //

    }
