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
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]
