Why it is not working. This code is for Disarium Number

public class sum
{
    public static void main (int num)
    {
        int i = 0;
        int sum = 0;
        String str = Integer.toString(num);
        int len = str.length();
        while (num > 0)
        {
            i = num%10;
            sum = sum + (int)Math.pow( i , len);
            len -- ;   // or len = len -1;
            num = num / 10;
        }
        
        if ( sum == num) 
        System.out.println("It is a Disarium Number");
        else
        System.out.println("It is not a Disarium Number");
    }
    
}

Design a class to Overload ......

Do we need to write main( ) ? If yes, do we have to get values from the user, or can we put in our own values? Getting from the user will be prettty loong..

why is (index of )answer -1 if character is not found in string ?

Can anyone help me with the code of my previous question.... I'll tell the logic for that as well..... 
The logic is: If you take the numerical value of the letters, you find that they are in fibonacci sequence. And the second half is reverse fibonacci. Remember to take the numeric value instead of ASCII value. Good luck coding!
