十进制转换为任意进制 java实现

今天在网上看到一个标题为“java实现的任意进制转换”的博客（http://ideasforjava.iteye.com/blog/636685），发现这篇博客并没有实现任意进制转换，如是自己就写了一个，跟大家分享一下

package interview;


import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Stack;


public class SwitchNumbers {

public static void main(String[] args) throws Exception, IOException
{
int num = 0;
int base = 0;
BufferedReader buf  = null;
System.out.print("请输入你要转换的数字:");
buf = new BufferedReader(new InputStreamReader(System.in));
num = Integer.parseInt(buf.readLine());//要转换的数字
System.out.print("请输入想要转换的进制:");
buf = new BufferedReader(new InputStreamReader(System.in));
base = Integer.parseInt(buf.readLine());//将转换为的进制
System.out.println(Switch(num,base));
}


public static String Switch(int num,int base) {
StringBuffer sb = new StringBuffer();
String all = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
String digths = all.substring(0, base);//将要转换的进制字母对应表
Stack<Character> s = new Stack<Character>();
while(num != 0)
{
s.push(digths.charAt(num%base));
num/=base;
}
while(! s.isEmpty())
{
sb.append(s.pop());
}
return sb.toString();
}
