java 汉字 拼音 java中实现汉字按照拼音排序(代码实例)

public static void main(String[] args) { 

  Comparator cmp = Collator.getInstance(java.util.Locale.CHINA);     

  String[] arr = { "张三", "李四", "王五", "刘六" ,"周濤","戴笠","戴阿"}; 
  String[] arr1 = {"生活","文教","政治","自然","宗教","經貿","軍事","经贸"}; 

//對簡體字有效，戴阿、戴笠在第一個字相同的情況下按拼音比較第二個字，很智能哦 
  Arrays.sort(arr, cmp); 
  for (int i = 0; i < arr.length; i++) 
//輸出：戴阿、戴笠、李四、刘六、王五、张三、周濤 
      System.out.println(arr[i]); 

//對繁體字無效，繁體的“軍事”被拍到了最后 
  Arrays.sort(arr1, cmp); 
  for (int i = 0; i < arr1.length; i++) 
      //輸出：经贸、生活、文教、政治、自然、宗教、經貿、軍事 
      System.out.println(arr1[i]);
