Java recursive function to convert decimal number to binary number

Write a java recursive function to convert the decimal number into binary number.

import java.util.*;
class DectoBin
{
    int convert(int n)
    {
        if(n==0)
        {
            return 0;
        }
        else
        {
            return (convert(n/2)*10+n%2);
        }
    }
    public static void main(String arr[])
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter Any Number in Decimal: ");
        int num=sc.nextInt();
        DectoBin obj=new DectoBin();
        int ans=obj.convert(num);
        System.out.println(num+" in Binary is : "+ans);        
    }
}

Enter Any Number in Decimal: 

8

8 in Binary is : 1000

Enter Any Number in Decimal: 

10

10 in Binary is : 1010
