Program: How to read objects from TreeSet using using Iterator?

Below example shows how to read objects using Iterator. By calling iterator() method you will get Iterator object, through which you can iterate through all the elements of the TreeSet.

package com.java2novice.treeset;

import java.util.Iterator;
import java.util.TreeSet;

public class MySetIteration {
	
	public static void main(String a[]){
		
		TreeSet<String> ts = new TreeSet<String>();
		ts.add("one");
		ts.add("two");
		ts.add("three");
		Iterator<String> itr = ts.iterator();
		while(itr.hasNext()){
			System.out.println(itr.next());
		}
	}
}

one
three
