What is the effect of adding the sixth element to a vector created in the following manner:

new Vector(5, 10);

An IndexOutOfBounds exception is raised.
The vector grows in size to a capacity of 10 elements
The vector grows in size to a capacity of 15 elements
Nothing, the vector will have grown when the fifth element was added
Select the most appropriate answer.

can anyone tell me what is the answer and why?

Ans: The vector grows in size to a capacity of 15 elements.
For Vector, the c'tor you're invoking is:

public Vector(int initialCapacity,
              int capacityIncrement)
  Constructs an empty vector with the specified initial capacity and capacity increment.
Parameters:
initialCapacity - the initial capacity of the vector.
capacityIncrement - the amount by which the capacity is increased when the vector overflows.
Throws:
IllegalArgumentException - if the specified initial capacity is negative

Initial capacity = 5
capacityIncrement = 10
When you added the 6th element, the Vector had to resize. It will add 10 to the current size (5) which gives 15.

the answer i believe is
The vector grows in size to a capacity of 15 elements
because the inital was 5 so whenever you go over it , it will be increased to 15 i think that if you go over that , the capacity will be increased proportionaly .
