实现发表金额转换（小写金额转换为大写金额）

import java.util.Scanner;
public class StringDemo5 {
    public static void main(String[] args) {
       /* 支票金额转换。小写转大写 还需要加上单位。*/

        //1.得到金额并进行判断
        Scanner sc = new Scanner(System.in);
        System.out.print("请输入金额：");
        int money = sc.nextInt();
        while (true) {
            if (money >= 0 && money <= 9999999){
                break;
            }else {
                System.out.println("金额无效！");
            }
        }

        // 定义一个变量来表示钱的大写
        String moneyStr = "";
        //2.得到每一个数字
        while (true) {
            // 从右往左，依次得到金额的个位
            int ge = money % 10;
            // 实现正序
            moneyStr =  getCapitalNumber(ge) + moneyStr;
            money = money / 10;
            if (money == 0){
                break;
            }
        }

        //3. 前面补零
        int count = 7 - moneyStr.length();
        for (int i = 0; i < count; i++) {
            moneyStr = "零" + moneyStr;
        }

        // 定义变量接收最终结果
        String result = "";
        // 4.补充单位
        String[] arr = {"佰", "拾", "万", "仟", "佰", "拾", "元"};
        for (int i = 0; i < moneyStr.length(); i++) {
            char c = moneyStr.charAt(i);
            result = result + c +arr[i];
        }
        System.out.println(result);

    }


    // 定义一个方法，实现小写转换为大写
    public static String getCapitalNumber(int number){
        // 定义数组，存储大写数字
        String[] bigNumber = {"零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"};
        return bigNumber[number];
    }
}
