Confusing SCJP 6 mock exam questions

Question

Given:
*class StringSplit {*
*public static void main(String [] args) {*
String s = "x1234 y56 z7 a";
String [] sa = s.split("\d");
int count = 0;
for( String x : sa)
count++;
System.out.println("total: " + count);
What is the result?
The "correct" answer for this question on the guide I'm using is 8.
I chose "Compilation Fails" based on my prior experience with other mock exams because some questions like these say that \d needs an extra \ (so \\d). For crying out loud, I even tested this code and it failed due to the missing escape.
Anyway, when I run into this type of question on the SCJP, and there's something like \d or \w or \s showing up, should I assume that it's a valid delimiter or assume that it's not escaped properly?
Thank you.
