 Getting
elements from the Vector
1) Object get(int index)
Returns the element at the specified index in the Vector.
Note : We need to downcast the returned object to the desired type.
2) Object firstElement()
Returns the first element of the Vector (i.e. at index 0)
3) Object lastElement()
Returns the last element of the Vector (i.e. at index size - 1)
Removing elements from the Vector
1) Object remove(int index)
Removes the elements at the specified index in the Vector and shifts
the subsequent element of the list by one. This method returns the
element that has been removed from the Vector. This method can throw
IndexOutOfBoundException if the index specified is out of range.
2) void removeElementAt (int index)
Removes the elements at the specified index in the Vector and shifts
the subsequent element of the list by one. This method can throw
ArrayIndexOutOfBoundException if the index specified is out of range.
3) boolean remove (Object object)
Removes the first occurrence of the specified Object from the Vector
if found. Returns true if the object is remove from the Vector,
otherwise returns false.
4) boolean removeElement (Object object)
Removes the first occurrence of the specified Object from the Vector
if found. Returns true if the object is remove from the Vector,
otherwise returns false.
5) boolean remove (Collection collection)
Remove all elements of the Vector which are found in the Collection
specified. Returns true if the Vector is changed, otherwise returns
false. This method can throw NullPointerException if the specified
Collection is null.
6) void removeRange(int startIndex, int endIndex)
Removes the elements from Vector whose index is between startIndex
inclusive and endIndex exclusive and shifts the subsequent elements
of the Vector.
7) void clear()
Removes all elements of the Vector.
8) void removeAllElements()
Removes all elements of the Vector.
Convert Vector in to an Object array
1) Object[] toarray()
Returns array of Object containing all elements of the Vector in
the correct order.
