java将数字转化为大写方法

// 日期转化为大小写
	public static String dataToUpper(String dateStr) {
		String res="";
		SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
		Date date = null;
		try {
			date = df.parse(dateStr);
		} catch (Exception e) {
			// 日期型字符串格式错误
			System.out.println("日期型字符串格式错误");
		}
		if(date!=null){
			Calendar ca = Calendar.getInstance();
			ca.setTime(date);
			int year = ca.get(Calendar.YEAR);
			int month = ca.get(Calendar.MONTH) + 1;
			int day = ca.get(Calendar.DAY_OF_MONTH);
			res=numToUpper(year) + "年" + monthToUppder(month) + "月"+dayToUppder(day) + "日";
		}
		return res;
	}

	// 将数字转化为大写
	public static String numToUpper(int num) {
		// String u[] = {"零","壹","贰","叁","肆","伍","陆","柒","捌","玖"};
		String u[] = { "〇", "一", "二", "三", "四", "五", "六", "七", "八", "九" };
		char[] str = String.valueOf(num).toCharArray();
		String rstr = "";
		for (int i = 0; i < str.length; i++) {
			rstr = rstr + u[Integer.parseInt(str[i] + "")];
		}
		return rstr;
	}

	// 月转化为大写
	public static String monthToUppder(int month) {
		if (month < 10) {
			return numToUpper(month);
		} else if (month == 10) {
			return "十";
		} else {
			return "十" + numToUpper(month - 10);
		}
	}

	// 日转化为大写
	public static String dayToUppder(int day) {
		if (day < 20) {
			return monthToUppder(day);
		} else {
			char[] str = String.valueOf(day).toCharArray();
			if (str[1] == '0') {
				return numToUpper(Integer.parseInt(str[0] + "")) + "十";
			} else {
				return numToUpper(Integer.parseInt(str[0] + "")) + "十"
						+ numToUpper(Integer.parseInt(str[1] + ""));
			}
		}
	}
