import java.util.Enumeration;

import java.util.Vector;

public class CreateArrayListFromEnumerationExample

{

public static void main(String[] args)

{

vector v = new Vector();

v.add("A");

v.add("B");

v.add("D");

v.add("E");

v.add("F");

System.out.println("Vector contains : " + v);

Enumeration e = v.elements(); 

ArrayList aList = Collections.list(e);

System.out.println("Arraylist contains : " + aList);         

   }

}

Create List containing n Copies of Specified Object

import java.util.Collections;

import java.util.List;

import java.util.Iterator;

public class CreateListOfNCopiesExample

 {

{

List list = Collections.nCopies(5,"A");

System.out.println("List contains, ");

Iterator itr = list.iterator();

while(itr.hasNext())

System.out.println(itr.next());

    }
