Java Stream - 如何使用Lambda排序列表

import java.util.Arrays;
import java.util.Collections;
import java.util.List;


public class Main {
  public static void main(String... args) {
    List<String> names = Arrays.asList("XML", "Java", "HTML", "CSS");
    Collections.sort(names, (String a, String b) -> b.compareTo(a));
    System.out.println(names);
    
    Collections.sort(names, (a, b) -> b.compareTo(a));
    System.out.println(names);
    
  }
}
