Write a program to check whether the given number is Happy Number or Not. #JAVA

/*
QUESTION : Write a program to check whether the givemn number is Happy Number or Not.
           A happy number is a number in which the eventual sum of the square of digits of the number is equal to 1.
           Example :
                        28 = 2^2 + 8^2
                             4 + 64 = 68
                        68 = 6^2 + 8^2
                             36 + 64 = 100
                        100 = 1^2 + 0^2 + 0^2
                             1 + 0 + 0 = 1

                number = sum;
            else
                break;
        }
        if(number == 1)
            System.out.println("Given number " + dNumber + " is happy number.");
        else
            System.out.println("Given number " + dNumber + " is not happy number.");

    }
}
