/** * 金额小数转换成中文大写金额 * @author Neil Han *	 */public class ConvertMoneyToUppercase {	private static final String UNIT[] = { "万", "千", "佰", "拾", "亿", "千", "佰",			"拾", "万", "千", "佰", "拾", "元", "角", "分" };	private static final String NUM[] = { "零", "壹", "贰", "叁", "肆", "伍", "陆",			"柒", "捌", "玖" };	private static final double MAX_VALUE = 9999999999999.99D;	/**	 * 将金额小数转换成中文大写金额	 * @param money	 * @return result	 */	public static String convertMoney(double money) {		if (money < 0 || money > MAX_VALUE)			return "参数非法!";		long money1 = Math.round(money * 100); // 四舍五入到分		if (money1 == 0)			return "零元整";		String strMoney = String.valueOf(money1);		int numIndex = 0; // numIndex用于选择金额数值		int unitIndex = UNIT.length - strMoney.length(); // unitIndex用于选择金额单位		boolean isZero = false; // 用于判断当前为是否为零		String result = "";		for (; numIndex < strMoney.length(); numIndex++, unitIndex++) {			char num = strMoney.charAt(numIndex);			if (num == '0') {				isZero = true;				if (UNIT[unitIndex] == "亿" || UNIT[unitIndex] == "万"						|| UNIT[unitIndex] == "元") { // 如果当前位是亿、万、元，且数值为零					result = result + UNIT[unitIndex]; //补单位亿、万、元					isZero = false;				} 			}else {				if (isZero) {					result = result + "零";					isZero = false;				}				result = result + NUM[Integer.parseInt(String.valueOf(num))] + UNIT[unitIndex];			}		}		//不是角分结尾就加"整"字		if (!result.endsWith("角")&&!result.endsWith("分")) {			result = result + "整";		}		//例如没有这行代码，数值"400000001101.2"，输出就是"肆千亿万壹千壹佰零壹元贰角"		result = result.replaceAll("亿万", "亿");		return result;	}	public static void main(String[] args) {		double value = Double.parseDouble("40330701101.2");		System.out.println("您输入的金额（小写）为：" + value);		System.out.println("您输入的金额（大写）为：" + convertMoney(value));	}}

输出为： 您输入的金额（小写）为：4.03307011012E10 您输入的金额（大写）为：肆佰零叁亿叁千零柒拾万壹千壹佰零壹元贰角
