Thread - TreeSet Iterator

[Sangita Mishra]

import java.util.*;
import java.util.TreeSet;
public class Thirsk{
    public static void main(String argv[]){
        Thirsk t = new Thirsk();
        t.a19();
    }
    public void a19(){
        TreeSet tm = new TreeSet();
        tm.add("Bill");
        tm.add("Kathy");
        tm.add("Carl");
        Iterator it = tm.iterator();
        while(it.hasNext()){
            System.out.print(tm.next()+ " ");
        }
    }
}[  

It's giving compile error. Can somebody please tell me what would be the exact metoh of TreeSet iterator in this case?

The TreeSet class does not have a method 'next', you need to call the method 'next' on the Iterator object. Check the API at,
TreeSet API

You need to make the following change for our code to compile, and show meangingful results,

 
while (it.hasNext()) {
System.out.print(it.next() + " ");
}
