Java character manipulation get pinyin for Chinese characters and other common tools

Company needs every year, this year a little special, haha.

Suddenly added a demand, said to achieve the Chinese character to pinyin query.

In the effort to write out, now share it!!!

/** * Kanji Pinyin abbreviation * * @param str * character string to convert * @return string phonetic abbreviation */public static string getpystring (String str) {String tempstr = ""; for (int i = 0; I < str.length (); i++) {char c = str.charat (i); if (c >= && C <= 126) {//letters and symbols remain as-is tempstr + = string.valueof (c);} else {//tired Add Pinyin initials TEMPSTR + = Getpychar (string.valueof (c));}} if (Tempstr.length () > 1) {tempstr = tempstr.substring (0, 1);} return TEMPSTR;} /** * Pinyin initials for single characters * * @param c *//single kanji to convert * @return String pinyin initials */public static string Getpychar (string c) {b yte[] Array = new Byte[2];array = String.valueof (c). GetBytes (); int i = (short) (Array[0]-' 256+ ' + n ') * ((short) (AR RAY[1]-' + + '), if (I < 0XB0A1) return "*", if (I < 0XB0C5) return "a", if (I < 0xb2c1) return "B"; if (I < 0x B4EE) return "C", if (I < 0XB6EA) return "D", if (I < 0XB7A2) return "E", if (I < 0XB8C1) return "F"; if (I < 0XB9FE) R Eturn "G"; if (I < 0XBBF7) return "H"; if (I < 0XBFA6) return "J"; if (I < 0xC0AC) return "K", if (I < 0xc2e8) return "L", if (I < 0XC4C3) return "M", if (I < 0XC5B6) return "n"; if (I < 0xc5be) re Turn "O", if (I < 0XC6DA) return "P", if (I < 0XC8BB) return "Q", if (I < 0XC8F6) return "R", if (I < 0xCBFA) return " S "; if (I < 0xCDDA) return" T ", if (I < 0XCEF4) return" W ", if (I < 0XD1B9) return" X ", if (I < 0xd4d1) return" Y "; if (I < 0XD7FA) return "Z"; return "*";} </textarea >

In addition, when doing the program, many times it is necessary to do time character translation, fill the next

The content of the article. Now give the corresponding time character conversion!!!

public static final String date_format = "Yyyy-mm-dd hh:mm";p ublic static final String date_format2 = "Yyyy-mm-dd HH:mm:ss ";p ublic static final String year_month_format =" yyyy-mm ";p ublic static final String date_format3 =" HH:mm:ss ";p u Blic static final String date_format1 = "YYYYMMDDHHMMSS"; /** * Time format with 24-hour */public static final string time_format = "hh:mm";/** * time date format without seconds */public static final string date_f Ormat_no_second = "Yyyy-mm-dd hh:mm";/** * is not the date format of the time */public static final String date_format_no_time = "YYYY-MM-DD"; Returns the corresponding time string public static string Getstrbydate (date date) {string str = ""; SimpleDateFormat SDF = new SimpleDateFormat (date_format); str = Sdf.format (DATE); return str;} Returns the corresponding time string public static string GetStrByDate2 (date date) {string str = ""; SimpleDateFormat SDF = new SimpleDateFormat (date_format); str = Sdf.format (DATE); return str;} Returns the corresponding time string public static string getStrByDate1 (date date) {string str = ""; SimpleDateFormat SDF = new SimpleDateFormat (DATE_FORMAT2); str = Sdf.format (DATE); return str;} /** * Convert Date to string format * * @param date * @return */public static string datetran2str (date date) {SimpleDateFormat DateFormat = New SimpleDateFormat (Strutil.date_format_no_second); return Dateformat.format (DATE);} /** * Convert Date to string format * * @param date * @return */public static string billrandom (date date) {SimpleDateFormat DateFormat = n EW SimpleDateFormat (STRUTIL.DATE_FORMAT1); return Dateformat.format (DATE);} /** * Convert Date to string format * * @param date * @param format date format * @return */public static string datetran2str (date date, string for MAT) {SimpleDateFormat DateFormat = new SimpleDateFormat (format); return Dateformat.format (date);} /** * Convert Date to string format * * @param date * @param format date format * @return */public static string Datetran2str (Object date, string f ormat) {SimpleDateFormat DateFormat = new SimpleDateFormat (format); return Dateformat.format (date);} /** * Convert Date to string format * * @param date * @param format date format * @return */public static string dateTran2STR (Object date) {SimpleDateFormat DateFormat = new SimpleDateFormat (date_format_no_second); return Dateformat.format ( date);} /** * Time format with seconds * * @param date * @param format date format * @return */public static String datetranstr2exc (Object date) {Simpleda Teformat DateFormat = new SimpleDateFormat (DATE_FORMAT2); return Dateformat.format (DATE);} /** * Converts a date string to a date * * @param datestr * Must be a date string that is turned around, otherwise there will be parseexception * @return null represents parseexception */p Ublic static Date strtran2date (String datestr) {try {return new SimpleDateFormat (Strutil.date_format_no_second).

"). GetMessage ());} return null;} /** * Convert the time of the database to a string * * @param t time * @return */public static string timetran2str (Object t) {SimpleDateFormat TimeFormat = New SimpleDateFormat (Time_format); String timestr = Null;timestr = Timeformat.format (t); return TIMESTR;} /** * Convert Timestamp to String * * @param timestampstring * @return */public static string Timestamp2date (String timestampstring) {Long timestamp = Long.parsELong (timestampstring) * 1000; String date = new Java.text.SimpleDateFormat ("Yyyy-mm-dd"). Format (new java.util.Date (timestamp)); return date;} public static string Strtranbirth (String day) {if (day.length () = = 8) {String y = day.substring (0, 4); String m = day.substring (4, 6); String d = day.substring (6, 8); return y + "-" + M + "-" + D;} Return day;}

Finally, we often have to do some of the characters for null judgments and the like, and other data of the regular

Expression validation, now also give benefits!!!

/** * Determines whether the input string parameter is empty * * @return Boolean NULL returns TRUE, non-null flase */public static Boolean isEmpty (string input) {return NULL = = Input | | 0 = = Input.length () | | 0 = = Input.replaceall ("\\s", "").
