java - 排序 LinkedHashMap

Question

鉴于 LinkedHashMap 包含字符串和整数，我如何根据其值对 LinkedHashMap 进行排序。所以我需要根据整数值对其进行排序。 非常感谢

Answer 1

List<Map.Entry<String, Integer>> entries =
  new ArrayList<Map.Entry<String, Integer>>(map.entrySet());
Collections.sort(entries, new Comparator<Map.Entry<String, Integer>>() {
  public int compare(Map.Entry<String, Integer> a, Map.Entry<String, Integer> b){
    return a.getValue().compareTo(b.getValue());
  }
});
Map<String, Integer> sortedMap = new LinkedHashMap<String, Integer>();
for (Map.Entry<String, Integer> entry : entries) {
  sortedMap.put(entry.getKey(), entry.getValue());
}
