    Vector and Array List both uses Array internally as data structure. They are dynamically re sizable. Difference is in the way they are internally re sized. By default, Vector doubles the size of its array when its size is increased. But, Array List increases by half of its size when its size is increased.

    Always read the API documentation:
    Vector (Java 2 Platform SE v1.4.2)
    ArrayList (Java 2 Platform SE v1.4.2)

    One major difference between the two is that one of them is synchronized: you may wish to avoid the overhead of synchronization if your application is single-threaded at the point of use of an object.
