Default Breaking a String

I have created an ID for any entity by concatenating 3 different IDs. I want to break them into 3 IDs again.For further elaboration the ID i wan to break is:

"CityID-CategoryID-SubcategoryID"

Now i want to break this ID into 3 again.Could someone give me some ideas.

Default

In perl:
my ($city,$cat,$subcat) = split /-/,$ID;

In Java, you could use a StringTokenizer:
import java.util.*;
/*do ID concatenation, etc...*/
StringTokenizer st = new StringTokenizer(ID,"-");
city = st.nextToken();
cat = st.nexttoken();
subcat = st.nextToken();
