    Default Re: collections

    Vector and array-list are better option for dynamically increase or decrease the array size.
    it depends on your requirement weather you are using multi-threaded environment or not.

    Default Re: collections

    If you must use arrays:
    create new array of the desired size
    copy contents of old array into the new array
    set the array reference variable to the new array.
