To check whether a number is a Krishna Murthy number or not

Question 44 : Write a program in Java to check whether the number given by the user is a Krishna Murthy number or not.

Krishna Murthy Number : It is a number which is equal to the sum of the factorials of all its digits.

For example : 145 = 1! + 4! + 5! = 1 + 24 + 120 = 145

Java Program : 

import java.io.*;
class krishnamurthy
{
 int fact(int n)
 {
     int i,p=1;
     for(i=n;i>=1;i--)
     p=p*i;
     return p;
    }
    void krishna()throws IOException
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        int a,b,s=0;
        System.out.print("Enter the number : ");
        a=Integer.parseInt(br.readLine());
        System.out.print("\n");
        int n=a;
        while(a>0)
        {
            b=a%10;
            s=s+fact(b);
            a=a/10;
        }
        if(s==n)
        System.out.print(n+" is a krishnamurthy number");
        else
        System.out.print(n+" is not a krishnamurthy number");
    }
}
