多选题 Given:
5. static String s = "";
6. public static void main(String[] args) {
7. try {doStuff(args); }
8. catch (Error e) {s += "e "; }
9. s += "x ";
10. System.out.println (s);
11. }
12. static void doStuff(String[] args) {
13. if(args.length == 0)
14. throw new IllegalArgumentException();
15. s += "d ";
16. }
And, if the code compiles, and given a java invocation with no arguments, what is the result? (Choose all that apply.)
