這篇文章主要介紹了java實(shí)現(xiàn)整數(shù)轉(zhuǎn)化為中文大寫(xiě)金額的方法，感興趣的小伙伴們可以參考一下

在日常生活中，我們經(jīng)常會(huì)將阿拉伯?dāng)?shù)字轉(zhuǎn)化為中文大寫(xiě)的情況："零", "壹", "貳", "叁", "肆", "伍", "陸", "柒", "捌", "玖", "拾", "佰", "仟", "萬(wàn)", "億"，因此自己就編寫(xiě)一個(gè)類(lèi)，實(shí)現(xiàn)該功能的轉(zhuǎn)化。
實(shí)現(xiàn)過(guò)程：
對(duì)于這個(gè)問(wèn)題的實(shí)現(xiàn)，我們首先把數(shù)字按四位一個(gè)拆開(kāi)（符合我們讀數(shù)字的習(xí)慣），然后對(duì)這四位數(shù)，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(gè) 
 if (g > 0) { 
  sb.append(NUMBER1[g]); 
 } 
 return sb.toString(); 
}

下面我們只需要在編寫(xiě)一個(gè)方法，實(shí)現(xiàn)每個(gè)四位數(shù)的讀法以及對(duì)應(yīng)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(wàn) 
 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(wàn)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(); 
}
