  B. ns = 50 S = 125 ns = 125 S = 125 ns = 0 S = 125

  C. ns = 50 S = 50 ns = 125 S = 125 ns = 100 S = 100

• Question 164:

  Which of the following exception will be thrown due to the statement given here?

  int array[] = new int[-2];

  A. NullPointerException

  B. NegativeArraySizeException

  C. ArrayIndexOutOfBoundsException

  D. IndexOutOfBoundsException

  E. This statement does not cause any exception.

  Correct Answer: B

  In given statement we can see that, we have passed negative value for creating int array, which results a NegativeArraySize Except ion. Hence option B is correct. Option A is incorrect as it is thrown when an application attempts to use null in a case where an object is required. Option D is incorrect as IndexOutOfBoundsException thrown to indicate that an index of some sort (such as to an array, to a string, or to a vector) is out of range.
