如何对Java Hashtable进行排序？

import java.util.*;

public class HashtableSortExample {
    public static void main(String[] args) {
        Hashtable<String, Integer> hashtable = new Hashtable<>();
        hashtable.put("A", 5);
        hashtable.put("B", 2);
        hashtable.put("C", 8);
        hashtable.put("D", 1);

        List<Map.Entry<String, Integer>> list = new ArrayList<>(hashtable.entrySet());

        // 按照键排序
        Collections.sort(list, new Comparator<Map.Entry<String, Integer>>() {
            public int compare(Map.Entry<String, Integer> o1, Map.Entry<String, Integer> o2) {
                return o1.getKey().compareTo(o2.getKey());
            }
        });

        // 按照值排序
        // Collections.sort(list, new Comparator<Map.Entry<String, Integer>>() {
        //     public int compare(Map.Entry<String, Integer> o1, Map.Entry<String, Integer> o2) {
        //         return o1.getValue().compareTo(o2.getValue());
        //     }
        // });

        LinkedHashMap<String, Integer> sortedHashtable = new LinkedHashMap<>();
        for (Map.Entry<String, Integer> entry : list) {
            sortedHashtable.put(entry.getKey(), entry.getValue());
        }

        System.out.println("排序后的Hashtable：" + sortedHashtable);
    }
}
