java实现 阿拉伯数字转换为汉字数字

public class VedioExtractSpeech {
	public static void main(String[] args) {
		System.out.println("toChinese："+toChinese("1230456"));
		System.out.println("toChinese2："+toChinese2("1230456"));
	}
	private static String toChinese(String str) {
	    String[] s1 = { "零", "一", "二", "三", "四", "五", "六", "七", "八", "九" };
	    String[] s2 = { "十", "百", "千", "万", "十", "百", "千", "亿", "十", "百", "千" };
	    String result = "";
	    int n = str.length();
	    for (int i = 0; i < n; i++) {
	        int num = str.charAt(i) - '0';
	        if (i != n - 1 && num != 0) {
	            result += s1[num] + s2[n - 2 - i];
	        } else {
	            result += s1[num];
	        }
	    }
	    return result;
	}
	private static String toChinese2(String str) {
		String[] s2 = {"零", "一", "二", "三", "四", "五", "六", "七", "八", "九"};
		StringBuffer sb=new StringBuffer();
		for (char c : str.toCharArray()) {
			sb.append(s2[Integer.parseInt(String.valueOf(c))]);
		}
	       return sb.toString();
	}
}

输出结果：

toChinese：一百二十三万零四百五十六
toChinese2：一二三零四五六
