How to copy elements of ArrayList to Java Vector

In order to copy elements of ArrayList to Java Vector, we use the Collections.copy() method. It is used to copy all elements of a collection into another.

Declaration −The java.util.Collections.copy() method is declared as follows −

public static <T> void copy(List<? super T> dest,List<? extends T> src)

where src is the source list object and dest is the destination list object

Let us see a program to copy elements of ArrayList to Java Vector −

Example

 Live Demo

import java.util.*;
public class Example {
   public static void main (String[] args) {
      List<String> zoo = new ArrayList<String>();
      zoo.add("Zebra");
      zoo.add("Lion");
      zoo.add("Tiger");
      Vector vect = new Vector();
      vect.add(1);
      vect.add(2);
      vect.add(3);
      Collections.copy(vect,zoo); // copying the ArrayList to the Vector
      System.out.println(vect);
   }
}

Output

[Zebra, Lion, Tiger]
