egoroff_w [7]

Answer:

Explanation:

The following code is written in Python. It creates a class that takes in one ArrayList parameter and loops through it and calls two functions that check if the numbers are Perfect, Odd, or Even. Then it goes counting each and printing the final results to the screen.

class NumberAnalyzer:

   def __init__(self, myArray):

       perfect = 0

       odd = 0

       even = 0

       for element in myArray:

           if self.isPerfect(element) == True:

               perfect += 1

           else:

               if self.isEven(element) == True:

                   even += 1

               else:

                   odd += 1

       print("# of Perfect elements: " + str(perfect))

       print("# of Even elements: " + str(even))

       print("# of Odd elements: " + str(odd))

   def isPerfect(self, number):

       sum = 1

       i = 2

       while i * i <= number:

           if number % i == 0:

               sum = sum + i + number / i

           i += 1

       if number == sum:

           return True

       else:

           return False

   def isEven(self, number):

       if (number % 2) == 0:

           return True

       else:

           return False
