使用Java程序如何让阿拉伯数字转换成中文?

import java.util.Scanner;

public class Num
{
public Num() {}

static String []bigNum={"零","一","二","三","四","五","六","七","八","九"};

static String getNUM(String str)
{

int t=Integer.parseInt(str);
return bigNum[t];
}

public static void main(String[] args)
{
try
{
String strbig=new String("");
System.out.print("请输入数字：");
Scanner sc=new Scanner(System.in);
long num=sc.nextLong();
String temp=String.valueOf(num);
int b=temp.indexOf(".");
int s=temp.length()-(b+1);

int j=b;
for (int i =0; i strbig+=getNUM(temp.substring(i,i+1));

j--;
}
temp=temp.substring(b+1,temp.length());
for (int i = 0; i < s; i++)
{

strbig+=getNUM(temp.substring(i,i+1));
}
System.out.println("转换结果："+strbig);
}
catch(Exception ex)
{
System.out.println("请输入整数");
}

}
}
