# The Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created.

Therefore, Vectors implement a dynamic array. This Tutorial Explains all about Vector Data Structure in Java With Examples. You will learn to Create, Initial, Sort & Use A Java Vector in your Programs: A vector can be defined as a dynamic array that can grow or shrink on its own i.e. vector will grow when more elements are added to it and will shrink when elements are removed from it.

How to read all elements in vector by using Enumeration? How to copy or clone a vector? How to add all elements of a list to vector? How to delete all elements from my vector?

It is recommended to use the Vector class in the thread-safe implementation only.

## Unlike array, we can store n-number of elements in it as there is no size limit. We can iterate over vector by the following ways: Simple for-loop; Enhanced for-loop; Iterators; Enumeration interface. Method 1: Simple for-loop. The idea is to run a for loop from start till the size of the vector. We can also iterate from n-1 to 0 to traverse in

It is inefficient to use a one-dimensional array to store a sparse vector. It is also inefficient to add elements whose values are zero in forming sums of sparse vectors. There are several ways to convert ArrayList to Vector.

We can also iterate from n-1 to 0 to traverse in A vector or arraylist is a one-dimensional array of elements. The elements of a Sparse Vector have mostly zero values. It is inefficient to use a one-dimensional array to store a sparse vector. It is also inefficient to add elements whose values are zero in forming sums of sparse vectors. There are several ways to convert ArrayList to Vector. We can use a vector constructor for converting ArrayList to vector.
