#61. Given:

 1. public class Foo { 
 2. public static void main(String[] args) { 
 3. String Buffer a = new StringBuffer (“A”); 
 4. String Buffer b – new StringBuffer (“B”); 
 5. operate (a, b); 
 6. System.out.printIn(a+ “,” + b); 
 7. } 
 8. Static void operate(StringBuffer x. String Buffer y) { 
 9. X.append(y); 
 10. y = x; 
 11. } 
 12. }

What is the result?

#62. Given:

 Integer i = new Integer (42); 
 Long l = new Long (42); 
 Double d = new Double (42.0);

Which two expression evaluate to true? (Choose two.)

#63. What is the numerical range of char?

#64. Given:

 1. public class Test { 
 2. public static void main (String [] args){ 
 3. String foo = args [1]; 
 4. String bar = args [2]; 
 5. String baz = args [3]; 
 6. System.out.printIn(“baz=”+baz): 
 7. } 
 8. }

and the output:
baz = 2
Which command line invocation will produce the output?

#65. Given:

 1. public interface Foo { 
 2. int k = 4: 
 3. }

Which three are equivalent to line 2? (Choose three)

#66. Given

 1. public class Foo { 
 2. public static void main (String [] args) } 
 3. try { return;} 
 4. finally { Syste.out.printIn (“Finally”);} 
 5. } 
 6. }

What is the result?

#67.

 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. page Context.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.?
