Copy All List Items to Vector in Java

This example shows how to create or copy a Vector with a collection of objects that inherits from the java.util.List. In this code, by using the addAll(), you can copy to another collection.

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

public class Copyallelements {

 public static void main(String[] args) {
 Vector< String>  vct = new Vector< String> (); 
 //add elements
 vct.add("first"); 
 vct.add("second"); 
 vct.add("third"); 
 vct.add("fourth"); 
 
 System.out.println("Before copy:"); 
 for(String e:vct)
 System.out.println(e); 
 
 List< String>  list = new ArrayList< String> (); 
 list.add("un"); 
 list.add("two"); 
 vct.addAll(list); 
 System.out.println("\nAfter copying: "); 
 for(String e:vct)
 System.out.println(e); 
 }
}

Runtime:

Before copy:
first
second
third
fourth

After copying:  
first
second
third
fourth
one
two
