public static boolean isSunny(int number) {

if(Math.sqrt(number+1)%1 == 0)

return true;

else return false;

}

// main method

public static void main(String[] args) {

// declare variables

int number = 0;

boolean result = false;

//create Scanner class object to take input

Scanner scan = new Scanner(System.in);

// take input from end-user

System.out.print("Enter an integer number::");

number = scan.nextInt();

// check number is Sunny number or not

result = isSunny(number);

// display result

if(result)

System.out.println(number +

" is a Sunny number.");

else

System.out.println(number +

" is not a Sunny number.");
