得到汉字的首字母问题(急,在线等待) 根据gb2312的区位码可以得到16-55区的首字母,对于56-87区的非常见汉字并不是按拼音排序的,请问要得到56-87区的汉字的拼音首字母该怎么做啊???? 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 http://blog.csdn.net/kevinliuu/archive/2006/06/28/846081.aspx --sunfruit 获得汉字的拼音首字母 源代码如下:/** * Title:获得汉字的拼音首字母 * Description: GB 2312-80 把收录的汉字分成两级。第一级汉字是常用汉字,计 3755 个, * 置于 16~55 区,按汉语拼音字母/笔形顺序排列;第二级汉字是次常用汉字, * 计 3008 个,置于 56~87 区,按部首/笔画顺序排列,所以本程序只能查到 * 对一级汉字的声母。同时对符合声母(zh,ch,sh)只能取首字母(z,c,s) * Copyright: Copyright (c) 2004 * Company: * @author not attributable * @version 1.0 */public class GetFirstLetter {// 国标码和区位码转换常量 private static final int GB_SP_DIFF = 160;//存放国标一级汉字不同读音的起始区位码 private static final int[] secPosvalueList = { 1601, 1637, 1833, 2078, 2274, 2302, 2433, 2594, 2787, 3106, 3212, 3472, 3635, 3722, 3730, 3858, 4027, 4086, 4390, 4558, 4684, 4925, 5249, 5600};//存放国标一级汉字不同读音的起始区位码对应读音 private static final char[] firstLetter = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'w', 'x', 'y', 'z'};//获取一个字符串的拼音码 public static String getFirstLetter(String oriStr) { String str = oriStr.toLowerCase();
