Consider the following code: 

1:class test
2:{
3:      public static void main (String args[])
4:      {
5:      double array [] = { -10.000, 2.4, -4.0, 0.1, 3.2, -0.9};
6:      int counter=0;
7:      for (int i=0; i < array.length; i++) {
8:        if (Math.floor (array[i] - 0.5) == Math.round (array[i] -Z)) counter--;
9:      }
10:     System.out.println ("Count=" + counter);
11:}
12:}
What should the value of Z be in line #8 if the output of the code is "Count=-6"?
A) 1
B) 0.5
C) 0
D) -1
E) None of the choices are correct

  • [ANS: A]

  • The Math.round () method add 0.5 to the argument and then performs a floor() operation. Therefore, the Math.round(array[i] - Z) is equivalent to Math.floor (array[i] - Z + 0.5).

    In this situation, the value of the counter will be decremented when its Math.floor (array[i] -0.5) value is equal to its Math.floor(array[i] - Z + 0.5) value.

    When Z=1, the comparison is as follows: Math.floor (array[i] - 1 + 0.5) = Math.floor (array[i] - 0.5).

    Therefore, when Z=1, the output of the code will be "Count= -6".
