java實現整數轉化為中文大寫金額的方法_mssql2008

在日常生活中，我們經常會將阿拉伯數字轉化為中文大寫的情況："零", "壹", "貳", "三", "肆", "伍", "陸", "柒", "捌", "玖", "拾", "佰", "仟", "萬", "億"，因此自己就編寫一個類，實現該功能的轉化。
實現過程：
對於這個問題的實現，我們首先把數字按四位一個拆開（符合我們讀數位習慣），然後對這四位元，做出他的讀法，具體代碼如下：

private static String getNumberStr1000 (int num) {  if (num > 9999 || num < 0) {   return "";  }  int q = num / 1000;  int b = (num / 100) % 10;  int s = (num / 10) % 10;  int g = num % 10;  StringBuffer sb = new StringBuffer();  //千  if (q > 0) {   sb.append(NUMBER1[q]);   sb.append(NUMBER2[3]);  }  //百  if (b > 0) {   sb.append(NUMBER1[b]);   sb.append(NUMBER2[2]);  } else {   if (q != 0) {    sb.append(NUMBER2[0]);   }  }  //十  if (s > 0) {   sb.append(NUMBER1[s]);   sb.append(NUMBER2[1]);  } else {   if (b != 0) {    sb.append(NUMBER2[0]);   }  }  //個  if (g > 0) {   sb.append(NUMBER1[g]);  }  return sb.toString(); } 

下面我們只需要在編寫一個方法，實現每個四位元的讀法以及對應的單位即可，具體代碼如下：

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();  //億  if (y > 0) {   sb.append(getNumberStr1000(y));   sb.append(NUMBER2[5]);  }  //萬  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]);   }  }  //萬以下  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(); }
