需求：金额转换，阿拉伯数字转换成中文传统形式，例如 101000001010 转为壹仟零壹拾亿零壹仟零壹拾圆整

最终版：

import java.util.Scanner;public class Test {public static void main(String[] args) {long num = 101000001010l;String[] digit ={"零","壹","貳","叁","肆","伍","陆","柒","扒","玖"};String[] unit = {"整","圆","拾","百","仟","万","拾","百","仟","亿","拾","百","仟","万"};while(true){num = new Scanner(System.in).nextLong();char[] chArr = Long.toString(num).toCharArray();StringBuilder sb = new StringBuilder("");for(int i = 0;i < chArr.length;i++){ String s = digit[Integer.parseInt(String.valueOf(chArr[i]))]; String s2 = unit[chArr.length-i]; sb.append(s).append(s2);  }sb.append(unit[0]);String str = sb.toString();str = change(str);System.out.println(str);}}private static String change(String str) {String s = str.replaceAll("零[仟百拾]", "零");s = s.replaceAll("零+", "零").replaceAll("零亿", "亿").replaceAll("零万", "万");s = s.replaceAll("零圆", "圆").replace("亿万", "亿");return s;}}
