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.

Q105. Given:
What would be the output, if it is executed as a program?
A. name =, pass =
B. name = null, pass = null
C. name = null, pass = false
D. name = null pass = true E. Compile error.
Answer: C
Explanation:
Both name and pass variables are instance variables, and we haven't given them any
values, so they take their default values. For Boolean default value is false and for string
which is not a primitive type default is null So at line 7, null will printed as the value of the
variable name, and at line 8 false will be printed. Hence Option C is correct.
As explained above options A, B and D are incorrect.
Code compiles fine so option E is incorrect.
