Java implements the method of converting integers into Chinese capital amounts _mssql2008

In daily life, we often convert Arabic numerals into Chinese capitals: "0", "one", "II", "three", "", "" WU "," Lu "," Qi "," ba "," Nine "," Pick Up "," Bai "," Qian "," million "," billion ", so he wrote a class, to achieve the transformation of the function 。
implementation process:
for the implementation of this problem, we first take the number four bits apart (consistent with our habit of reading the numbers), and then to the four digits, make his reading, the specific code is as follows:

private static String getNumberStr1000 (int num) { 
 if (num > 9999 | | | num < 0) {return 
  ""; 
 } 
 int q = num/1000; 
 int b = (num/100)%; 
 int s = (NUM/10)%; 
 int g = num%; 
 StringBuffer sb = new StringBuffer (); 
 Thousand 
 if (q > 0) { 
  sb.append (number1[q]); 
  Sb.append (Number2[3]); 
 Hundred 
 if (b > 0) { 
  sb.append (number1[b]); 
  Sb.append (number2[2]); 
 else { 
  if (q!= 0) { 
   sb.append (number2[0]); 
  } 
 Ten 
 if (S > 0) { 
  sb.append (number1[s]); 
  Sb.append (number2[1]); 
 else { 
  if (b!= 0) { 
   sb.append (number2[0]); 
  } 
 An 
 if (G > 0) { 
  sb.append (number1[g]); 
 } 
 return sb.tostring (); 
} 

Below we only need to write a method to implement each four-digit reading and corresponding units, the specific code is as follows:

 public static String getnumberstr (int num) {if (num < 0) {return "; 
 } if (num = = 0) {return number1[0]; 
 int split = 10000; 
 int y = num/(split * split); 
 int w = (num/split)% split; 
 int g = num% split; 
 StringBuffer sb = new StringBuffer (); 
  billion if (Y > 0) {sb.append (getNumberStr1000 (y)); 
 Sb.append (Number2[5]); 
  //million if (W > 999) {sb.append (getNumberStr1000 (w)); 
 Sb.append (Number2[4]); 
   else {if (W > 0) {if (y!= 0) {sb.append (number2[0]); 
   } sb.append (getNumberStr1000 (w)); 
  Sb.append (Number2[4]); 
   }//below if (G > 0) {if (w!= 0) {if (G > 999) {sb.append (getNumberStr1000 (g)); 
    else {sb.append (number2[0]); 
   Sb.append (getNumberStr1000 (g)); 
   } else {if (y!= 0) {sb.append (number2[0]); 
  } sb.append (getNumberStr1000 (g)); 
} return sb.tostring (); }
