java数字转中文金额

以下是Java实现中文金额的示例代码：

public static String numberToChinese(double number) {
    String[] units = new String[]{"", "万", "亿", "万亿"};
    String[] nums = new String[]{"零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"};
    String[] cents = new String[]{"角", "分"};
    long temp = Math.round(number * 100);
    int numIndex = 0;
    int unitIndex = units.length - 1;
    boolean isZero = true;
    StringBuilder builder = new StringBuilder();
    while (temp != 0) {
        int digit = (int) (temp % 10);
        if (digit != 0) {
            builder.insert(0, units[unitIndex]);
            builder.insert(0, nums[digit]);
            isZero = false;
        } else {
            if (!isZero) {
                builder.insert(0, nums[digit]);
            }
            isZero = true;
        }
        temp /= 10;
        numIndex++;
        if (numIndex % 4 == 0) {
            unitIndex--;
        }
    }
    if (builder.length() == 0) {
        builder.append(nums[0]);
    }
    builder.append("元");
    temp = Math.round(number * 100);
    int centIndex = 0;
    while (temp != 0 && centIndex < cents.length) {
        int digit = (int) (temp % 10);
        if (digit != 0) {
            builder.append(nums[digit]).append(cents[centIndex]);
        }
        temp /= 10;
        centIndex++;
    }
    if (builder.length() == 1) {
        builder.append(nums[0]).append("角");
    }
    return builder.toString();
}

示例调用：

System.out.println(numberToChinese(123456789.12)); // 输出：壹亿贰仟叁佰肆拾伍万陆仟柒佰捌拾玖元壹角贰分

代码说明：

该实现将数字按照“亿、万、个”的单位进行分组，然后将每组的数字转成中文表示。在转换过程中，将0省略，同时在每个数字后面添加相应的单位。最后将整数部分和小数部分拼接起来，返回中文金额的字符串表示。
