栈的应用数制转换

package littlejava;

import java.util.Stack;

public class MultiBaseOutput {

    public static void main(String[] args)
    {
        int N=256,B=2;
        bandConvert(N,B);
    }
    public static String bandConvert(int N,int B)
    {
         Stack stack=new Stack();
         int i;
         while(N!=0)
         {
             i=N%B;
             N=N/B;
             stack.push(i);
         }
         String str="";
         while(!stack.isEmpty())
         {
             str+=stack.pop();
         }
         System.out.println(str);
         return str;
    }
