java输入数字输出中文

以下是一个 Java 程序，可以将输入的数字转换为中文大写：

import java.util.Scanner;

public class NumberToChinese {
    private static final String[] CN_NUM = { "零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖" };
    private static final String[] CN_UNIT = { "", "拾", "佰", "仟" };
    private static final String[] CN_SECTION = { "", "万", "亿", "万亿" };

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("请输入一个数字：");
        long num = sc.nextLong();
        System.out.println(numberToChinese(num));
    }

    public static String numberToChinese(long num) {
        if (num == 0) {
            return CN_NUM[0];
        }
        String result = "";
        int section = 0;
        while (num > 0) {
            int n = (int) (num % 10000);
            if (n != 0) {
                String s = "";
                int unit = 0;
                while (n > 0) {
                    int d = n % 10;
                    if (d != 0) {
                        s = CN_NUM[d] + CN_UNIT[unit] + s;
                    } else if (!s.startsWith(CN_NUM[0])) {
                        s = CN_NUM[0] + s;
                    }
                    n /= 10;
                    unit++;
                }
                result = s + CN_SECTION[section] + result;
            } else {
                if (!result.startsWith(CN_NUM[0])) {
                    result = CN_NUM[0] + result;
                }
            }
            num /= 10000;
            section++;
        }
        return result;
    }
}

当输入一个数字时，程序会将其转换为中文大写并输出。例如，输入 123456789，输出壹亿贰仟叁佰肆十五万陆仟柒佰捌十九。
