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
