Demo Question 11.

11. public class Iterate Handler extends Body Tag Support { 12. private Collection c: 13. private Iteator it: 14. public void set coll (collection c) {this.c+ c;} 15. public int do Start Tag () throws Jsp Exception { 16. // insert code here 17. } 18. public void dolnit Body () throws Jsp Exception { 19. it = c. iterator (): 20. pageContext.set Attribute ("item" it.next()); 21. } 22. public int do After Body () throuws Jsp Exception { 23. if (it. Has Next ()){ 24. page Context.set Attribute ("item", it.next ()); 25. // insert code here 26. } else { 27. try { 28. get Body Content (). Write Out (get Previous Out ()); 29. } catch (Exception e) {} 30. // insert code here 31. } 32. } 33. } Given that the loop tag properly iterates over Collection assigned to its cool attribute. <mx: loop coll = <% = a Collection %> > <jsp: use Bean id= "item" scope =" page class = "java. Lang. String"/> </mx:loop> Which additions needs to be made to the Iterate Handler class for it to properly perform as the tag handler for the loop tag.?

A. Insert return c. is Empty () ? EVAL_BODY_AGAIN:SKIP_BODY: at line 16 Insert return EVAL_BODY_AGAIN: at line 25. Insert return SKIP_BODY: At line 30.
B. Insert return c. is Empty ()? SKIP_BODY: EVAL_BODY_AGAIN: at line 16 Insert return SKIP_BODY: at line 25. Insert return EVAL_BODY_AGAIN: at line 30
C. Insert return c. is Empty () ? EVAL_BODY_AGAIN : SKIP BODY: at line 16 Insert return EVAL_BODY_AGAIN: at line 25. Insert return SKIP_BODY: at line 30.
D. Insert return c. is Empty ()? EVAL_BODY_AGAIN:SKIP_BODY: at line 16 Insert return SKIP_BODY: at line 25. Insert return EVAL_BODY_AGAIN: at line 30
