No, afaik the switch statement in Java needs a simple scalar type such as
int or char.
I suggest you use if...else if.

I forgot to paste it in:
String dept = rset.getString(DEPARTMENT); from my Oracle Query
switch(dept) {
case FAO:
out.println(It\'s FAO.);
break;
case CAO:
out.println(It\'s CAO.);
break;
case RES:
out.println(It\'s RES.);
break;
default:
Java doesn't allow you to use anything other than integer (or castable
to integer) values for switch statements, so strings can't be sued.
With a switch that small, I recommend a series of if statements
String s=department.trim().toUpperCase();
if (s.equals(FAO)) rate=0.09;
else if
It seems to be kind of poor not to be able to use switch on a string. If I
