将数字转为中文金额的大写方式(Java版)
以下是一个简单的RMB人民币类的Java代码,实现了将金额转换为中文大写形式字符串的功能:
```
public class RMB {
private static final char[] RMB_NUMS = {'零','壹','贰','叁','肆','伍','陆','柒','捌','玖'};
private static final char[] RMB_UNITS = {'元','拾','佰','仟','万','拾','佰','仟','亿'};
private static final char RMB_DECIMAL = '点';
public static String toChinese(double amount) {
StringBuilder sb = new StringBuilder();
long yuan = (long) amount;
int jiao = (int) ((amount - yuan) * 10);
int fen = (int) ((amount - yuan - jiao * 0.1) * 100);
if (yuan == 0) {
sb.append(RMB_NUMS[0]);
} else {
int unitIndex = 0;
while (yuan > 0) {
int num = (int) (yuan % 10);
if (num > 0 || unitIndex == 0 || sb.charAt(sb.length() - 1) != RMB_NUMS[0]) {
sb.append(RMB_NUMS[num]).append(RMB_UNITS[unitIndex]);
}
yuan /= 10;
unitIndex++;
}
}
if (jiao == 0 && fen == 0) {
sb.append("整");
} else {
if (jiao > 0) {
sb.append(RMB_NUMS[jiao]).append("角");
}
if (fen > 0) {
sb.append(RMB_NUMS[fen]).append("分");
}
}
return sb.toString();
}
}
```
可以使用该类的静态方法`toChinese`将金额转换为中文大写形式字符串。例如:
```
double amount = 123.45;
String rmb = RMB.toChinese(amount);
System.out.println(rmb); // 壹佰贰拾叁元肆角伍分
```
