 Sample 1. Write a Program that gets a set of numbers , filters out the non prime numbers , calculate the factorial of each prime number and then finds the average of all factorials using Lambda expressions

public class BuggyBread1 {
   public static void main(String args[]) {
      // Declare and Initialize the Collection
      Set<Integer> intSet = new HashSet<Integer>();

      // Add Elements

      double averageOfNonPrimeFactorials =>checkIfPrime(p)).collect(Collectors.averagingInt(p->calculateFactorial(p)));
      System.out.println(averageOfNonPrimeFactorials );
   static private boolean checkIfPrime(int num){
      for(int count=2;count < num;count++){
         if(num % count == 0){
            return false;
      return true;
   static private int calculateFactorial(int num){
      int factorial = 1;
      for(int count=num;count > 0;count--){
         factorial = factorial * count;
      return factorial;
