Java implements two classes for converting Renminbi numbers into uppercase letters

To convert a Renminbi number into a Chinese character, we only need to use a relatively fixed method, that is, write the numbers in uppercase 1-10, and then store them in an array before comparison and conversion, the method does not have any advanced algorithms. It is very simple. For more information, see.

Method 1: Convert RMB numbers into Chinese capital prices using java

The Code is as follows:

Copy code

Package xwcms.net. service; Import java. util. HashMap; /** * Convert the numeric amount to the Chinese capital amount * @ Author ftpeng * */ Public class test { /** * RMB capital Unit System */ Private static HashMap <Integer, String> dws; /** * Numbers correspond to Chinese Characters */ Private static String [] jes; // Initialization execution Static { Dws = new HashMap <Integer, String> (); Dws. put (-2, "points "); Dws. put (-1, ""); Dws. put (0, "Yuan "); Dws. put (1, "pick up "); Dws. put (2, "success "); Dws. put (3, "success "); Dws. put (4, "Ten Thousand ");// Dws. put (5, "Pick "); Dws. put (6, "success "); Dws. put (7, "success "); Dws. put (8, "");// Dws. put (9, "Pick "); Dws. put (10, "success "); Dws. put (11, "success "); Dws. put (12, "Ten Thousand "); Jes = new String [] {"zero", "one", "two", "three", "Si", "Wu", "Lu", "Lu ", "identifier", "identifier "}; } /** * Convert numbers into uppercase letters * @ Param number the number does not support scientific numbers * @ Return */ Public static String chinese (String number ){ StringBuffer su = new StringBuffer (); // Integer part Number = delInvalidZero (number ); String str = null; // Decimal part String decimal = null; If (number. contains (".")){ // Truncate an integer Str = number. split ("\.") [0]; Decimal = number. split ("\.") [1]; } Else { Str = number; } // Determine whether an integer exists If (str. length ()> 0 ){ For (int I = 0; I <str. length (); I ++ ){ String context = str. substring (I, I + 1 ); Int pow = str. length ()-i-1; Integer val = Integer. parseInt (context. toString ()); // Obtain the Chinese Unit String sign = dws. get (pow ); // Obtain Chinese numbers String name = jes [Integer. parseInt (context)]; If (val = 0 ){ If (pow % 4! = 0) {// Delete Unit Sign = ""; } If (I <str. length ()-1 ){ Integer val1 = Integer. parseInt (str. substring (I + 1, I + 2 )); If (val = 0 & val = val1 ){ Name = ""; } } Else if (I = str. length ()-1 ){ Name = ""; } } Su. append (name + sign ); } } // Determine whether there are decimal places If (decimal! = Null ){ Str = decimal. substring (0, 1 ); If (! "0". equals (str )){ Su. append (jes [Integer. parseInt (str)] + dws. get (-1 )); } If (decimal. length () = 2 ){ Str = decimal. substring (1, 2 ); If (! "0". equals (str )){ Su. append (jes [Integer. parseInt (str)] + dws. get (-2 )); } } } Else { Su. append ("whole "); } Return su. toString (); } /** * Clear special numeric characters * @ Param str * @ Return */ Private static String delInvalidZero (String str ){ If ("0". equals (str. substring (0, 1 ))){ Return delInvalidZero (str. substring (1, str. length ())); } Else if (str. contains (",")){ Return delInvalidZero (str. replaceAll (",","")); } Else { Return str; } } Public static void main (String [] args ){ System. out. println (test. chinese ("12.5 ")); } }

Method 2,

 

The Code is as follows:

Copy code

Package test; Import java. text. DecimalFormat; Public class Test { Private static final String digit_0 = ""; Private static final String digit_1 = "0 August 5, 1234 "; Private static final String [] digit_2 = {"", "10", "hundreds", "thousands "}; Private static final String [] digit_3 = {"", "Pick", "success", "success "}; Private static final String [] digit_4 = {"", "trillion "}; /** * @ Param args */ Public static void main (String [] args ){ System. out. println (changeDigit ("2012.12", false )); System. out. println (changeDigit ("210.12", true )); System. out. println (changeNumberRMB (210.12 )); } /** * Description: converts a number to an integer. * @ Param str * @ Param bo * @ Return */ Public static String changeDigit (String str, boolean bo ){ StringBuffer strbu = new StringBuffer (); Int dou = str. indexOf ("."); //: Determines whether it is a decimal or an integer.
