简介 java实现整数转化为中文大写金额的方法_mssql2008_

在日常生活中，我们经常会将阿拉伯数字转化为中文大写的情况："零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖", "拾", "佰", "仟", "万", "亿"，因此自己就编写一个类，实现该功能的转化。
实现过程：
对于这个问题的实现，我们首先把数字按四位一个拆开（符合我们读数字的习惯），然后对这四位数，做出他的读法，具体代码如下：

 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]); } } //个 if (g > 0) { sb.append(NUMBER1[g]); } return sb.toString(); }

下面我们只需要在编写一个方法，实现每个四位数的读法以及对应的单位即可，具体代码如下：

 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(); //亿 if (y > 0) { sb.append(getNumberStr1000(y)); sb.append(NUMBER2[5]); } //万 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]); } } //万以下 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(); }

完整源代码：

 /** *@Description: */ package com.lulei.util; public class NumberUtil { private static String[] NUMBER1 = {"零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"}; private static String[] NUMBER2 = {"零", "拾", "佰", "仟", "万", "亿"}; /** * @param num * @return * @Author:lulei * @Description:将数字转化为大写 */ 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(); //亿 if (y > 0) { sb.append(getNumberStr1000(y)); sb.append(NUMBER2[5]); } //万 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]); } } //万以下 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(); } /** * @param num * @return * @Description:对万以下的数字进行大小写转化 */ 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]); } } //个 if (g > 0) { sb.append(NUMBER1[g]); } return sb.toString(); } public static void main(String[] args) { // TODO Auto-generated method stub int i = 1; System.out.println(i + "--" + NumberUtil.getNumberStr(i)); i = 1001; System.out.println(i + "--" + NumberUtil.getNumberStr(i)); i = 100101; System.out.println(i + "--" + NumberUtil.getNumberStr(i)); i = 10100101; System.out.println(i + "--" + NumberUtil.getNumberStr(i)); i = 1234567890; System.out.println(i + "--" + NumberUtil.getNumberStr(i)); } }
