the question is what shall i assume in exam autoboxing is there or not?
this entry in errata says its not there-
HFSJ 2nd edition
Page 847
Question 39 - Answer D
The question reads:
Given req is a reference to a valid HttpServletRequest, and:
13.
String[] s = req.getCookies();
14. Cookie[] c = req.getCookies();
15. req.setAttribute("myAttr1", "42");
16. req.setAttribute("myAttr2", 42);
17. String[] s2 = req.getAttributeNames();
18. String[] s3 = req.getParameterValues("attr");
Which lines of code will not compile? (Choose all that apply.)
A. line 13
B. line 14
C. line 15
D. line 16
E. line 17
F. line 18
The soultion says that Answer D is not correct. "-Option D: setAttribute() takes a String and an Object, and as of
Java 5, 42 can be boxed to an Object."
While this may be true for Java 5, this exam does not
test on Java 5 as noted on page xxviii of the book: "About the SCWCD (for Java EE 1.5) exam The updated SCWCD exam is called "Sun Certified Web Component Developer for the Java Platform, Enterprise Edition 5" (CX-310-083), but don't get confused by the title.
The updated exam is still designed for Java EE v1.4 and for the
servlet v2.4 and
JSP v2.0 specifications." Which means autoboxing does not exist and Answer D IS correct. Line 16 will not compile.
Note from the Author or Editor:
Agreed. Drop option D and line 16 from the question here and on pg 811
errata of hf 2nd edition
So what shall I assume for the exam?
