數字大寫轉換java

1. 如何用java編一個程序將輸入的阿拉伯數字轉換成大寫的漢字

import java.util.HashMap;
import java.util.Scanner;

public class Convert {
public static void main(String[] args) {
HashMap<Integer, String> hashMap = new HashMap<Integer, String>();
hashMap.put(0, "零");
hashMap.put(1, "壹");
hashMap.put(2, "差搭貳"轎團);
hashMap.put(3, "叄");
hashMap.put(4, "肆");
hashMap.put(5, "伍");
hashMap.put(6, "陸");
hashMap.put(7, "柒");
hashMap.put(8, "捌");
hashMap.put(9, "虛帆拿玖");
Scanner scanner = new Scanner(System.in);
String input = scanner.next();
for (int i = 0; i < input.length(); i++) {
System.out.print(hashMap.get(input.charAt(i) - 48));
}
}
}

2. java 數字轉大寫漢字

/**只貼修改的formatTo(int money)方法這一部分了,希望有幫助*/
public void formatTo(int money) {
Map<Integer, String> moneyMap = new HashMap<Integer, String>();
Map<Integer, String> moneyMap2 = new HashMap<Integer, String>();
StringBuffer sb = new StringBuffer();

String moneyString = (money + "").trim().toString();
int moneyLength = moneyString.length();
num = moneyLength;
//標記上一層是否為零
boolean isPrevNumberZero = false;
for (int i = 0; i < moneyLength; i++) {
Character c = moneyString.charAt(i);
Integer key = Character.getNumericValue(c);
// 如果是0 跳過,並把isPrevNumberZero設為true
if(key == 0 ){

num--;
continue;

//如果上層是0,則sb字元串增加一個零
if(isPrevNumberZero){
