import java.util.ArrayList;

import java.util.Enumeration;

Parameters:

c - the collection for which an enumeration is to be returned.

*/


public class CollectionsExample
{

public static void main(String[] args)
{

ArrayList<Integer> arrayList = new ArrayList<Integer>();

arrayList.add(2000);
arrayList.add(3000);
arrayList.add(4000);

System.out.println("arrayList : " + arrayList + "\n");

/*
* Returns an enumeration over the specified collection.
* This provides interoperability with legacy APIs that require
* an enumeration as input.
*/

Enumeration<Integer> enumeration = Collections.enumeration(arrayList);

while (enumeration.hasMoreElements())
{
Integer value = enumeration.nextElement();
System.out.println(value);

}

}

}
Output
arrayList : [2000, 3000, 4000]

2000
3000
