This article mainly introduces an example of the tool class that converts the amount of yuan to 10,000 yuan in java, which has a good reference value, and I hope it will be helpful to everyone. Let's follow the editor to take a look
I won't talk too much nonsense, everyone should look at the code directly~
public static void main(String[] args) {
// 具体的金额（单位元）
String value = "88000067898";
BigDecimal bigDecimal = new BigDecimal(value);
// 转换为万元（除以10000）
BigDecimal decimal = bigDecimal.divide(new BigDecimal("10000"));
// 保留两位小数
DecimalFormat formater = new DecimalFormat("0");
// 四舍五入
formater.setRoundingMode(RoundingMode.HALF_UP);
// 格式化完成之后得出结果
String formatNum = formater.format(decimal);
System.out.println(formatNum);
}
/**元转万元且四舍五入取整*/
public static String getNumberWan(String value) {
BigDecimal bigDecimal = new BigDecimal(value);
// 转换为万元（除以10000）
BigDecimal decimal = bigDecimal.divide(new BigDecimal("10000"));
// 保留两位小数
DecimalFormat formater = new DecimalFormat("0");
// 四舍五入
formater.setRoundingMode(RoundingMode.HALF_UP);
// 格式化完成之后得出结果
String rs = formater.format(decimal);
return rs;
}
/**元转万元且保留两位小数并四舍五入*/
public static String getNumberWanTwo(String value) {
BigDecimal bigDecimal = new BigDecimal(value);
// 转换为万元（除以10000）
BigDecimal decimal = bigDecimal.divide(new BigDecimal("10000"));
// 保留两位小数
DecimalFormat formater = new DecimalFormat("0");
// 四舍五入
formater.setRoundingMode(RoundingMode.HALF_UP);
// 格式化完成之后得出结果
String rs = formater.format(decimal);
return rs;
}
Supplement: Use java to convert the amount from a number to a digital amount in Chinese
Write an amount converted from a number to a number in Chinese
E.g:
123123.12 converted to one ten thousand two thousand three thousand one hundred two ten three yuan one dime two cents
Since the code is copied directly from the development process, some of it can be ignored. The newcomer has just worked and the writing is not good. Please correct me.
