Write a program to print perfect numbers between 1 and 500.

Perfect numbers are numbers that are equal to the sum of its proper divisors. Ex:- 6 has proper divisors-> 1,2,3 And 6 = 1 + 2 + 3. Therefore, 6 is a perfect number.

do you want us to write a program?? public class Program { public static void main(String[] args) { System.out.println("perfect numbers between 1 and 500 are "); for (int z = 2; z <= 500; z ++ ){ int prenum = perfectnumber(z); if (prenum != 0){ System.out.println(prenum) ; } } } public static int perfectnumber(int x){ int y=0; for (int count =1 ; count < x; count++){ if (x % count == 0) { y += count ; } // close if } // close for if (y == x) { return y; } else { return 0; } } }
