Q:

Can I use a range of values in a single switch?

I'm trying to simplify a Card class, and am wondering if there's any way to use a range of values in a switch statement?
CONSIDER:
 if((card<14))
     suit="Hearts";
     else
     if((card>14)&&(card<27))
         suit="Clubs";

             etc.

Instead I'd like to use a switch statement, such as:
switch(card){
    case1: through case13:
    suit="Hearts";
    break;

       etc.

I wasn't able to find anything in the Java Tutorials that suggest there is such a variation of switch. But is there?

A:

About the best you can do is something like this (see below). So in some cases (no pun intended :)), it's just better to use an if statement.
switch(card){
    case 1:
    case 2:
    case 3:
    case 4:
    case 5:
    case 6:
    case 7:
    case 8:
    case 9:
    case 10:
    case 11:
    case 12:
    case 13:
        suit="Hearts";
        break;
}

However, another approach you could consider is using a map.
Map<Integer, String> map = new HashMap<Integer, String>();
for (int i = 1; i <= 14; ++i) {
  map.put(i, "Hearts");
}
for (int i = 15; i <= 26; ++i) {
  map.put(i, "Clubs");
}

Then you can look up the card's suit using the map.
String suit1 = map.get(12); // suit1 will be Hearts after the assignment
String suit2 = map.get(23); // suit2 will be Clubs after the assignment

Java doesn't allow you to do any such thing unfortunately. Other JVM languages might though, i.e., Scala.
