Create a PerfectIntegers application that displays all perfect integers up to 500. A perfect integer is a number which is equal to the sum of all its factors except itself. For example, 6 is a perfect number because all the factors of 6 (which are less than 6) are 1, 2 and 3; and 1 + 2 + 3 = 6. In your code, your main() method must call the boolean method isPerfect().
