java 数字转中文

java代码 数字转中文,该方法只做了对int型整数的转换

private static String numberToChinese(int number) {
String[] numbers = {"零", "一", "二", "三", "四", "五", "六", "七", "八", "九"};
String[] units = {"", "十", "百", "千", "万", "十", "百", "千", "亿", "十"};
String sign = number < 0 ? "负" : "";
if (number < 0) {
number = -number;
}
StringBuilder result = new StringBuilder(sign);
String string = String.valueOf(number);
int n = string.length();
char[] numberCharArray = string.toCharArray();
for (int i = 0; i < n; i++) {
int digNum = n - i; // 位数
int num = numberCharArray[i] - '0';
if (num != 0) {
result.append(numbers[num]).append(units[digNum - 1]);
continue;
} if (result.toString().endsWith(numbers[0])) {
// 如果是单位所在的位数，则去除上一个0，加上单位
if (digNum % 4 == 1) {
result.deleteCharAt(result.length() - 1);
result.append(units[digNum - 1]);
}
}else{
result.append(numbers[0]);
}
}
return result.toString();
}
