What is difference between ArrayList and vector ?

ArrayList :  1. It is non-synchronised or not threadsafe
                     2. The default size of ArrayList is 10
                     3. When 11th element is inserted the size of ArrayList increases by 50%
                     4. We can not use Enumeration to traverse ArrayList.

Vector    :   1.  It is synchronised or threadsafe
                    2.  The default size of vector is 10
                    3. When 11th element is inserted the size of vector increases by double
                    4. We can  use Enumeration to traverse vector.
