能不能调整下规范，添加一下注释

public class DescSortDemo{
public static void main(String[] args){
var s = new String[]{"China", "England","France","America","Russia",};
Set ts = new TreeSet<> ();
for (var i = 0; i < s.length; i ++)
ts.add(s[i]);
System.out.println(ts); ts = new TreeSet<>(new Comparator(){
public int compare(String a, String b){
return b.compareTo(a);
}
}
);
for (int i = 0; i < s.length; i ++)
ts.add(s[i]);
System.out.println(ts);
}
}

你先这样，然后那样，再然后不就出来了

同学，作业就自己做吧
