Java에서 TreeSet을 반복하는 방법은 몇 가지입니까?

import java.util.*;
public class IteratingTreeSetTest {
   public static void main(String[] args) {
      Set<String> treeSetObj = new <strong>TreeSet</strong><String>();
      treeSetObj.add("Ramesh");
      treeSetObj.add("Adithya");
      treeSetObj.add("Jai");
      treeSetObj.add("Vamsi");
      treeSetObj.add("Chaitanya");
      <strong>Iterator<String></strong> it = treeSetObj.iterator(); // <strong>Iterator interface</strong>
      while (it.<strong>hasNext()</strong>) {
         System.out.println(<strong>it.next()</strong>);
      }
   }
}
