int array[] = new int[-2];
A. NullPointerException
B. NegativeArraySizeException
C. ArrayIndexOutOfBoundsException
D. IndexOutOfBoundsException
E. This statement does not cause any exception.
Answer: B
Explanation:
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.
