Program :- 

import java.io.*; import java.util.*; class Sunny {     public static void main(String args[])     {             Scanner in = new Scanner(System.in);         int n,i,a,c=0;         System.out.println("Enter Number : ");         n= in.nextInt(); // Input Number         for(i=1;i<=n;i++)         {             a= (i*i)-1; //storing square of an integer with 1 less value             if(a==n)             {                 c=1; // storing 1 if the condition is satisfied             }         }         if(c==1)         {             System.out.println("It is a Sunny Number : "+n);         }         else         {             System.out.println("It is not a Sunny Number : "+n);         }     } // end of main method } // end of class
