在Java中列出文件的最佳方法是按日期修改排序？

我想获取一个目录中的文件列表，但是我想对它进行排序，以便最旧的文件是第一个。我的解决方案是调用File.listFiles，只是根据File.lastModified打开列表，但是我想知道是否有更好的方法。

I want to get a list of files in a directory, but I want to sort it such that the oldest files are first. My solution was to call File.listFiles and just resort the list based on File.lastModified, but I was wondering if there was a better way.

编辑：我当前的解决方案根据建议，使用匿名比较器：

My current solution, as suggested, is to use an anonymous Comparator:

File[] files = directory.listFiles();

Arrays.sort(files, new Comparator<File>(){
    public int compare(File f1, File f2)
    {
        return Long.valueOf(f1.lastModified()).compareTo(f2.lastModified());
    } });
