      To copy elements of Java Vector to Java ArrayList use,
      static void copy(List dstList, List sourceList) method of Collections class.
    
      This method copies all elements of source list to destination list. After copy index of the elements in both source and destination lists would be identical.
    
      The destination list must be long enough to hold all copied elements. If it  is longer than that, the rest of the destination list's elments would remain
      unaffected.     
    */
  
    System.out.println("Before copy ArrayList Contains : " + arrayList);
  
    //copy all elements of Vector to ArrayList using copy method of      Collections  class
    Collections.copy(arrayList,v);
  
    /*
      Please note that, If ArrayList is not long enough to hold all elements of
      Vector, it throws IndexOutOfBoundsException.
    */

    System.out.println("After Copy ArrayList Contains : " + arrayList);

}

Output:
Before copy ArrayList Contains : [One, Two, Three, Four, Five]
After Copy ArrayList Contains : [1, 2, 3, Four, Five]
