Q. What will be the output of the following code

import java.util.Comparator;

public class SortSet {
public static void main(String…a)
{
Set<Integer> treeSet=new TreeSet(new Comparator<Integer>()
{
public int compareTo(Integer o1,Integer o2)
{
return o2.compareTo(o1);
}
});
treeSet.add(3);
treeSet.add(1);
treeSet.add(2);
System.out.println(treeSet);

}

}
