前言：
输入数字金额参数，运行程序得到其对应的大写中文金额；例如：输入— 12.56，输出— 12.56:壹拾贰元伍角陆分；
奉上代码：
/**

* @date: 2019年6月18日 下午10:52:27
*/
public class ConvertUpMoney {
//大写数字
private static final String[] NUMBERS = {"零","壹","贰","叁","肆","伍","陆","柒","捌","玖"};
// 整数部分的单位
private static final String[] IUNIT = {"元","拾","佰","仟","万","拾","佰","仟","亿","拾","佰","仟","万","拾","佰","仟"};
//小数部分的单位
private static final String[] DUNIT = {"角","分","厘"};
//转成中文的大写金额
public static String toChinese(String str) {
//判断输入的金额字符串是否符合要求
if (StringUtils.isBlank(str) || !str.matches("(-)?[\\d]*(.)?[\\d]*")) {
System.out.println("抱歉，请输入数字！");
return str;
}
if("0".equals(str) || "0.00".equals(str) || "0.0".equals(str)) {

}
//判断是否存在负号"-"
boolean flag = false;
if(str.startsWith("-")){
flag = true;
str = str.replaceAll("-", "");
}
str = str.replaceAll(",", "");//去掉","
String integerStr;//整数部分数字
String decimalStr;//小数部分数字
//初始化：分离整数部分和小数部分
if(str.indexOf(".")>0) {

}else if(str.indexOf(".")==0) {

}
//beyond超出计算能力，直接返回

System.out.println(str+"：超出计算能力");
return str;
}
int[] integers = toIntArray(integerStr);//整数部分数字
//判断整数部分是否存在输入012的情况
if (integers.length>1 && integers[0] == 0) {
System.out.println("抱歉，请输入数字！");
if (flag) {
str = "-"+str;
}
return str;
}
boolean isWan = isWan5(integerStr);//设置万单位
int[] decimals = toIntArray(decimalStr);//小数部分数字
String result = getChineseInteger(integers,isWan)+getChineseDecimal(decimals);//返回最终的大写金额
if(flag){
return "负"+result;//如果是负数，加上"负"
}else{
return result;
}
}
//将字符串转为int数组
private static int[] toIntArray(String number) {
int[] array = new int[number.length()];
for(int i = 0;i1 && integers[i+1]!=0) {
key += NUMBERS[0];
}
}
chineseInteger.append(integers[i]==0?key:(NUMBERS[integers[i]]+IUNIT[length - i -1]));
}
return chineseInteger.toString();
}
//将小数部分转为大写的金额
private static String getChineseDecimal(int[] decimals) {
StringBuffer chineseDecimal = new StringBuffer("");
for(int i = 0;i 4) {
String subInteger = "";
if(length > 8) {
subInteger = integerStr.substring(length- 8,length -4);
}else {
subInteger = integerStr.substring(0,length - 4);
}
return Integer.parseInt(subInteger) > 0;
}else {
return false;
}
}
//Test
public static void main(String[] args) {
String number = "12.56";
System.out.println(number+": "+ConvertUpMoney.toChinese(number));
