Creates a new Vector with initialCapacity equals to 100 and capacityIncrement equals to 0.

3) Vector (Collection c)
Creates a new vector containing elements of the specified collection in the order returned by the Collection’s Iterator.

Example

Where myCollection is the Object of type Collection.

4) Vector (int initialCapacity, int capacityIncrement)
