The code below gives you an example of converting a Set into a List. It simply done by creating a new instance of List and pass the Set as the argument of the constructor.
package org.kodejava.example.util;
import java.util.*;
public class SetToList {
public static void main(String[] args) {
//
// Create a Set and add some objects into the Set.
//
Set<Object> set = new HashSet<Object>();
set.add("A");
set.add(new Long(10));
set.add(new Date());
//
// Convert the Set to a List can be done by passing the Set instance into
// the constructor of a List implementation class such as ArrayList.
//
List<Object> list = new ArrayList<Object>(set);
for (int i = 0; i < list.size(); i++) {
Object o = list.get(i);
System.out.println("Object = " + o);
}
}
}
