Java implementation Digital amount converted to Chinese capital amount

We often do the project's financial statements, need to print invoices and other situations need to use the lower case financial amount to convert the capital amount of Chinese characters, the following is the code to implement the function

Import Java.lang.Math;

/**
* General-purpose Money conversion class
*
*/
public class Money {
Private String handigistr[] = new string[] {"0", "one", "Ii.", "three", "the", "WU",
"Lu", "Qi", "ba", "JIU"};
Private String handivistr[] = new string[] {"", "Pick", "Bai", "Thousand", "Million", "pick",
"Bai", "Qian", "billion", "Pick Up", "Bai", "Qian", "Million", "Pick", "Bai", "Qian", "billion", "pick", "Bai",
"Thousand", "Million", "Pick", "Bai", "Thousand"};
/**
* @param numstr Input string must be a positive integer, only leading spaces (must be right justified), should not have leading zeros
* @return
*/
String Positiveintegertohanstr (String numstr) {
String rmbstr = "";
Boolean Lastzero = false;
Boolean hasvalue = false; MJ digits are marked before
int Len, n;
Len = Numstr.length ();
if (Len > 15)
Return "value too big!";
for (int i = len-1; I >= 0; i--) {
if (Numstr.charat (len-i-1) = = ")
Continue
n = Numstr.charat (Len-i-1)-' 0 ';
if (N < 0 | | n > 9)
Return "input with non-numeric characters!";

if (n! = 0) {
if (Lastzero)
Rmbstr + = handigistr[0]; Some 0 followed by a non-0 value, showing only one 0
Except for hundreds of billions of years ago, 0 didn't bring back.
if (!) (N==1 && (i%4) ==1 && (Lastzero | | i==len-1))//
If there are 0 before the decimal, do not send a tone with this line
if (! ( n = = 1 && (i% 4) = = 1 && i = = len-1))//10 carry in the first position does not send a sound
Rmbstr + = Handigistr[n];
Rmbstr + = Handivistr[i]; Non-0 value plus carry, single digit is empty
HasValue = true; Value tag before placing MJ bit

} else {
if ((i% 8) = = 0 | | ((i% 8) = = 4 && hasvalue)) Hundreds of billions must have a non-0 value to show million
Rmbstr + = Handivistr[i]; "Million" or "million"
}
if (i% 8 = = 0)
HasValue = false; MJ bit pre-value mark million reset
Lastzero = (n = = 0) && (i% 4! = 0);
}

if (rmbstr.length () = = 0)
return handigistr[0]; Enter a null character or "0" and return "0"
return rmbstr;

}
