本文提供了一种将长数字转换为中文金额表示的方法，并通过一个具体的Java类实现该功能。该类可以处理从个位数到包含万亿级别的大数字，并能正确地在中文金额中使用单位如“万”、“亿”。代码示例展示了如何将数字2212023003400转换成对应的中文表示。

面试遇到的，当时写的不好，回来整理一下思路，写出来后还算满意。

public class Test {
    private String[] unit = { "", "十", "百", "千" };
    private String[] segmentUnit = { "", "万", "亿", "万亿", "亿亿" };
    private String[] num = { "零", "一", "二", "三", "四", "五", "六", "七", "八", "九" };

    public String numberToChNumber(long numberm) {
        String str = "";
        char[] numChar = (new StringBuffer("" + numberm).reverse().toString()).toCharArray();
        int segment = (numChar.length - 1) / 4 + 1;
        for (int segmentIndex = 1; segmentIndex <= segment; segmentIndex++) {
            str = segmentUnit[segmentIndex - 1] + str;
            int start = (segmentIndex - 1) * 4;
            for (int j = 0; j <= 3; j++) {
                int index = start + j;
                if (index < numChar.length) {
                    if (numChar[index] == 48 && index == start) {
                        continue;
                    } else if (numChar[index] == 48 && numChar[index - 1] == 48) {
                        continue;
                    } else if (numChar[index] == 48 && numChar[index - 1] != 48) {
                        str = num[numChar[index] - 48] + str;
                    } else {
                        str = num[numChar[index] - 48] + unit[j] + str;
                    }
                }
            }
        }
        return str;
    }

    public static void main(String[] args) {
        System.out.println(new Test().numberToChNumber(new Long("2212023003400")));
    }
