program to convert decimal numbers to another base does not work correctly

I wrote this program to convert decimal numbers to another bases but when I run it with eclipse the answer is 0 for any number.

import java.util.Scanner;

public class dtb {
    public static void main(String[] args) {
        Scanner myscanner = new Scanner (System.in);
        int num= myscanner.nextInt();
        int base= myscanner.nextInt();  
        int i=0;
        int y=0;
        while (num >= base){
            int x = (num%base);
            num = num/base;

            y = (y + (x*(10^i)));   
        }
        System.out.println (y) ;
    }
}

The ^ operator doesn't do what you think. If you want to elevate to a power, use Math.pow():

Math.pow(10, i)

but since this method returns a double, you will have to cast it to int:

(int) Math.pow(10, i)

Check your input. you num value should be greater than base value. eg: 30,20 output is 100.
