Java - How to Convert a Vector to an ArrayList

This example shows how to convert from Vector to ArrayList. We proceed as follows: create a Vector that contains Strings and then create an ArrayList from this Vector.

In the following code, we have a Vector that contains String objects and we are in the process of converting it into an ArrayList of Strings. First, we create a Vector filled with String elements and second, the step of converting from Vector to ArrayList using the Vector object as an argument in the declaration of the ArrayList.

import java.util.ArrayList; 
import java.util.List; 
import java.util.ListIterator; 
import java.util.Vector; 

public class VectorToArrayList {

 public static void main(String[] args) {
 Vector< String> vec = new Vector< String> (); 
 //insert elements
 vec.add("o1"); 
 vec.add("o2"); 
 vec.add("o3"); 
 
 System.out.println("Vector Elements:"); 
 for(String e:vec)
 System.out.println(e); 
 
 //ArrayList declarioin initialized with Vector
 List< String> arraylist = new ArrayList< String> (vec); 

 System.out.println("ArrayList:"Elements); 
 for(String e:arraylist)
 System.out.println(e); 
 }
}

Runtime:

Vector Elements:
o1
o2
o3
ArrayList:
o1
o2
o3
