Write the java program:

An integer number is said to be a perfect number if its

factors, including 1 (but not the number itself), sum to the

number. For example, 6 is a perfect number, because 6 = 1

+ 2 + 3. Write a method isPerfect that determines whether

parameter number is a perfect number. Use this method

in an application that displays all the perfect numbers

between 1 and x, where x is entered by the user.
