JavaでTreeSetを降順に並べ替える方法は?

输入: Set: [2, 3, 5, 7, 10, 20]
输出: Set: [20, 10, 7, 5, 3, 2]

输入: Set: [computer, for, geeks, hello]
输出: Set: [hello, geeks, for, computer]

import java.util.TreeSet; 
  
public class TreeSetDescending { 
  
    public static void main(String[] args) 
    { 
        // 声明一个treeset
        TreeSet<Object> ints = new TreeSet<Object>(); 
        ints.add(2); 
        ints.add(20); 
        ints.add(10); 
        ints.add(5); 
        ints.add(7); 
        ints.add(3); 
  
        TreeSet<Object> intsReverse = (TreeSet<Object>)ints.descendingSet(); 
  
        // Print the set 
        System.out.println("Without descendingSet(): " + ints); 
        System.out.println("With descendingSet(): " + intsReverse); 
    } 
}

Without descendingSet(): [computer, for, geeks, hello]
With descendingSet(): [hello, geeks, for, computer]
