运用短除法

上图为转换为二进制的过程，转换为x进制就将2换成x。

 1 import java.util.Scanner;
 2 
 3 public class Change {
 4 
 5     public static void main(String[] args) {
 6         // TODO Auto-generated method stub
 7         Scanner cin = new Scanner(System.in);
 8         System.out.print("输入待转换的数和待转换的进制：");
 9         int OldNum = cin.nextInt();//待转换成10进制的数
10         int x = cin.nextInt();//待转换数的进制
11         int num = ten2x(OldNum, x);
12         System.out.println(num);
13     }
14     
15     public static int ten2x(int n, int x) {
16         int num = 0;
17         int k =1;
18         while(n!=0) {
19             int m = n % x;
20             num += m*k;
21             n = n / x;
22             k *= 10;
23         }    
24         return num;
25     }
26 }
