Program:

import java.util.TreeSet;
import java.util.Iterator;
public class TreeSetDemo {
public static void main(String[] args) {
TreeSet ts = new TreeSet();
ts.add(“A”);
ts.add(“E”);
ts.add(“C”);
ts.add(“B”);
ts.add(“D”);
System.out.println(“TreeSet: “+ts);
Iterator it = ts.iterator();
System.out.print(“TreeSet-element: “);
while(it.hasNext())
System.out.print(” “+it.next());
}
}

Result:

TreeSet: [A, B, C, D, E]
TreeSet-element:  A B C D E
