如何用java,javascript,python获取中文的拼音首字母？

最近需要实现拼音首字母搜索，顺便整理一下其他语言的拼音首字母搜索的代码进行备用，有需要的直接拿走。话不多说，直接上码

JavaScript，只保留了核心的提取拼音的部分，如果需要可以留下邮箱或者私信我

第一种:

直接上代码(有个别中文无法识别):

import java.io.UnsupportedEncodingException; /** * * @author yuki_ho * */ public class ChineseCharToEnUtil { private final static int[] li_SecPosValue = { 1601, 1637, 1833, 2078, 2274, 2302, 2433, 2594, 2787, 3106, 3212, 3472, 3635, 3722, 3730, 3858, 4027, 4086, 4390, 4558, 4684, 4925, 5249, 5590 }; private final static String[] lc_FirstLetter = { "a", "b", "c", "d", "e", "f", "g", "h", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "w", "x", "y", "z" }; /** * 取得给定汉字串的首字母串,即声母串 * @param str 给定汉字串 * @return 声母串 */ public String getAllFirstLetter(String str) { if (str == null || ().length() == 0) { return ""; } String _str = ""; for (int i = 0; i < (); i++) { _str = _str + (i, i + 1)); } return _str; } /** * 取得给定汉字的首字母,即声母 * @param chinese 给定的汉字 * @return 给定汉字的声母 */ public String getFirstLetter(String chinese) { if (chinese == null || c().length() == 0) { return ""; } chinese = (chinese, "GB2312", "ISO8859-1"); if () > 1) // 判断是不是汉字 { int li_SectorCode = (int) c(0); // 汉字区码 int li_PositionCode = (int) c(1); // 汉字位码 li_SectorCode = li_SectorCode - 160; li_PositionCode = li_PositionCode - 160; int li_SecPosCode = li_SectorCode * 100 + li_PositionCode; // 汉字区位码 if (li_SecPosCode > 1600 && li_SecPosCode < 5590) { for (int i = 0; i < 23; i++) { if (li_SecPosCode >= li_SecPosValue[i] && li_SecPosCode < li_SecPosValue[i + 1]) { chinese = lc_FirstLetter[i]; break; } } } else // 非汉字字符,如图形符号或ASCII码 { chinese = (chinese, "ISO8859-1", "GB2312"); chinese = c(0, 1); } } return chinese; } /** * 字符串编码转换 * @param str 要转换编码的字符串 * @param charsetName 原来的编码 * @param toCharsetName 转换后的编码 * @return 经过编码转换后的字符串 */ private String conversionStr(String str, String charsetName,String toCharsetName) { try { str = new String(charsetName), toCharsetName); } catch (UnsupportedEncodingException ex) { Sy("字符串编码转换异常：" + ex.getMessage()); } return str; } public static void main(String[] args) { ChineseCharToEnUtil cte = new ChineseCharToEnUtil(); Sy("获取拼音首字母："+ c("广州")); } }

第二种:

所需包:net.sourceforge.pinyin4j import net.; import net.; import net.; import net.; import net.; import net.; /** * * @author yuki_ho * @time 2017-07-25 */ public class ChineseCharToEnUtil { /** * 将字符串中的中文转化为拼音,其他字符不变 * * @param inputString * @return */ public static String getPingYin(String inputString) { HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat(); ); ); ); char[] input = in().toCharArray(); String output = ""; try { for (int i = 0; i < in; i++) { if (input[i]).matches("[\\u4E00-\\u9FA5]+")) { String[] temp = PinyinHel(input[i], format); output += temp[0]; } else output += java.lang.C(input[i]); } } catch (BadHanyuPinyinOutputFormatCombination e) { e.printStackTrace(); } return output; } /** * 获取汉字串拼音首字母，英文字符不变 * @param chinese 汉字串 * @return 汉语拼音首字母 */ public static String getFirstSpell(String chinese) { StringBuffer pybf = new StringBuffer(); char[] arr = c(); HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat(); de); de); for (int i = 0; i < arr.length; i++) { if (arr[i] > 128) { try { String[] temp = PinyinHel(arr[i], defaultFormat); if (temp != null) { (temp[0].charAt(0)); } } catch (BadHanyuPinyinOutputFormatCombination e) { e.printStackTrace(); } } else { (arr[i]); } } return ().replaceAll("\\W", "").trim(); } /** * 获取汉字串拼音，英文字符不变 * @param chinese 汉字串 * @return 汉语拼音 */ public static String getFullSpell(String chinese) { StringBuffer pybf = new StringBuffer(); char[] arr = c(); HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat(); de); de); for (int i = 0; i < arr.length; i++) { if (arr[i] > 128) { try { (PinyinHel(arr[i], defaultFormat)[0]); } catch (BadHanyuPinyinOutputFormatCombination e) { e.printStackTrace(); } } else { (arr[i]); } } return (); } public static void main(String[] args) { String cnStr = "努力的椰子"; Sy("努力的椰子-->" + getPingYin(cnStr)); String s = getFirstSpell("努力的椰子"); Sy("努力的椰子-->" + s); StringBuffer sb = new StringBuffer(s); if () > 1) { String ss = (1, ()).toString(); Sy("努力的椰子-->" + C()[0]) + ""); } } }

python
