Question

10. Which of the following correcthy milites elements each with value 0? super Bass to com I inttl superBass { 0, 0, 0, 0, 0 ); int(1 superBass = new int [5] inttl superBass = new int (5) for (int i = 0; i < super Bass.length superBass ) = 0; +) (A) (B) I only II only I and II only I and III only I. II, and III (D) (E) 17. Consider the following Java program public class ReferenceMysteryi ! public static void main(String[] args) { int x = 0; int[] a = new int [B]: x = x + 2; mystery (x, a); x = x + 2; mystery (x, a); public static void mystery(int x, int[] a) { x = x + 1; a [x] = a[x] + 1; What are the values in the array a after the main method has finished? (A) (B) (C) (D) (E) { 0, 0, 0, 1, 0, 1, 0, 0) { 0, 0, 0, 0, 0, 0, 0, 0) { 0, 0, 0, 1, 0, 0, 0, 1) { 0, 0, 1, 0, 1, 0, 0, 0) { 0, 0, 1, 1, 0, 0, 0, 0)

Answer 1

16. In all the three ways array is initialized to contain five zero's.

option E.

-------------------------------

17. x becomes 2;

mystery(2,a)
this call updates a[3]=a[3]+1;
  
mystery(4,a)
this call updates a[5]=a[5]+1;
  
the contents of array a={0,0,0,1,0,1,0,0}

Answer is :option A

-----------------------------------------------

18. int[ ][ ] twoDimensionalArray=new int[2][3];
This declares two twoDimensionalArraywith 2 rows and 3 columns.
Answer: option B

option A is wrong because it declares 3 rows and 2 columns and option C is not syntactically correct.

--------------------------------------------------------------------

19. option C

i==arr.length

20. Its always true, either first condition or second condition is true.option B

------------------------------

21,Answer option D {result=4}

22. Answer option C x={3,3,3,1,1}

result = 3, Initially 1-o; calculate A ( 3 x) 2[3] = a (312) 12; x[1]/2 x [3] =312=1 / 3,3,3,1,3} a[3/2] + x[3] x[i] + 12 =4 [first return value] i=1; Calculate A ( 4, x) *[4] = * [412]/2 - M[2]/2 * [u] = 3/2=1 /= {3,3,3,1,13 return value x[4/2] + x[4] [3+1=4e return value.
