java之金额大小写转换

代码如下，但是感觉不太好。

 

public class MoneyConvert
{
    private final String[] str1 = {"元", "拾", "佰", "仟", "万", "拾", "佰", "仟", "亿"};
    private final String[] str2 = {"零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"};
    private final String[] str3 = {"角", "分"};

    public static void main(String[] args)
    {
        double n = 1234506.789;

        MoneyConvert mc = new MoneyConvert();
        String str = mc.convert(n);

        System.out.println(str);
    }

    public String convert(double n)
    {
        String str = String.valueOf(n);
        String temp1 = str.substring(0, str.indexOf("."));
        String temp2 = str.substring(str.indexOf(".")+1);

        int k = -1;
        int len = -1;
        StringBuffer sb = new StringBuffer();

        len = temp1.length()-1;
        for(int i=0; i<temp1.length(); i++)
        {
            k = Integer.parseInt(temp1.substring(i, i+1));
            sb.append(str2[k]).append(str1[len-i]);
        }

        for(int i=0; i<2; i++)
        {
            k = Integer.parseInt(temp2.substring(i, i+1));
            sb.append(str2[k]).append(str3[i]);
        }

        return sb.toString();
    }
}

输出为：

 

壹佰贰拾叁万肆仟伍佰零拾陆元柒角捌分
