Java Program to check Number is Perfect or Not ?

A perfect number is a positive integer that is equal to the sum of its positive divisors, that is, the sum of its positive divisors excluding the number itself.

For Example The first perfect number is 6, because 1, 2, and 3 are its positive divisors, and sum of  1 + 2 + 3 = 6. Other Perfect Numbers are 28 ,496 and so on.

public class PerfectNumber {

public static boolean isNumPerfect(int num){
boolean status = false;
int temp = 0;
for(int i=1;i<=num/2;i++){
if(num%i == 0){
temp+= i;
}
}
if(temp == num){
status = true;
} else{
status = false;
}
return status;
}
public static void main(String[] args) {
System.out.println("Is 6 Perfect Number : "+PerfectNumber.isNumPerfect(6));
System.out.println("Is 28 Perfect Number : "+PerfectNumber.isNumPerfect(28));
System.out.println("Is 30 Perfect Number : "+PerfectNumber.isNumPerfect(30));
}
}

Program Output :-

Is 6 Perfect Number : true
Is 28 Perfect Number : true

Is 30 Perfect Number : false
