I don't think it's a good idea to use that Java 5! language feature. It can lead to poor traceability and to error-prone code. Instead I would always use collections. What do you think?
Here's an example in case someone else missed out on it too:
public class VarargTest {
public static void func(String p1, String... args) {
for(String arg : args) System.out.println(arg);
}
public static void main(String args[]) {
func("a");
func("a","b");
func("a","b","c");
}
}
