用JAVA写的一个十进制转换任意进制数的程序

import java.io.*;

public class TEST1 {
    public static void main(String args[]) throws IOException
    {
        int count = 0;
        byte buff[] = new byte[1024];
        count = System.in.read(buff);
        String strings = new String(buff, 0, count);
        String string[] = strings.split(",");
        int num = Integer.parseInt(string[0].trim());
        int m = Integer.parseInt(string[1].trim());

        int arr[] = new int[1024];


        //System.out.println(num);
        //System.out.println(m);

        count = 1023;
        while(num > 0)
        {
            arr[count] = num%m;
        //    System.out.println(arr[count]);
            count--;
            num = num/m;
        }
        for(;count < 1023; count++)
            if(arr[count+1] < 10)
                System.out.print(arr[count+1]);
            else
            {
                char ch = (char)(arr[count+1]-10+65);
                System.out.print(ch);
            }
    }
}
