    {
        String s;
        if (x == 0)
                s = "zero";
        else
                s = "non-zero";

String s;
switch (x) {
case 0:  s = "zero"; break;
default:  s="non-zero";
}
return s;


2.   If-else is better in this case.   Swtich is better when the alternative would be if-else if-else if-else if-else if-else if-else if-else  (that is, a LOT of cases)
