Vector implements List Interface. Like ArrayList it also maintains insertion order but it is rarely used in non-thread environment as it is synchronized and due to which it gives poor performance in searching, adding, delete and update of its elements. The java.util.Vector class implements a growable array of objects. Similar to an Array, it contains components that can be accessed using an integer index. Following are the important points about Vector − The size of a Vector can grow or shrink as needed to accommodate adding and removing items.
// preallocated vector, which can hold 100 elements Vector integers = new Vector(100); . // default vector, which will probably grow a couple of times when adding 100 element Vector integers = new Vector(); A true Java array cannot grow or shrink, and it doesn't support removal of an element from a mid-point.
