java 仿windows文件排序

public class FileSortUtils {

    public static void main(String[] args) {
        File file = new File("F:\\file");
        List<File> list = Arrays.asList(file.listFiles());
        list.forEach(f -> System.out.println(f.getName()));
        System.out.println("----------");
        List<File> sort = sort(list);
        sort.forEach(f -> System.out.println(f.getName()));
    }

    public static List<File> sort(List<File> list) {
        List<File> sortFile = new ArrayList<>();
        //文件夹集合
        List<File> folderList = list.stream().filter(file -> file.isDirectory()).collect(Collectors.toList());
        //文件集合
        List<File> fileList = list.stream().filter(file -> file.isFile()).collect(Collectors.toList());
        //文件夹排序
