Question

Why wont my java program print out anything past "please enter a group of at least 5 integers"?

import java.util.Scanner;

public class MyStatistics {

   public static void main(String[] args) {
       // TODO Auto-generated method stub

       Scanner sc=new Scanner(System.in);
       System.out.println("Please enter a group of at least 5 integers.");
      

       String count_val = sc.nextLine();
       int[] int_array = new int[5];
       int sum_val = 0;
       int mean_val = 0;
       System.out.println("Your input has " + count_val.split(" ").length + " numbers");
      
       //Input 5 Numbers
       for(int x = 0; x < 10; x++){
       int_array[x] = sc.nextInt();
       }
      
      
       //Find the sum
       for(int x = 0; x < 10; x++){
       sum_val = sum_val + int_array[x];
       }

      

       //Find the average
       for(int x = 0; x < 5; x++){
       mean_val = sum_val + int_array[x];
       }
      
      
       System.out.println("The sum is: " + sum_val);
       System.out.println("The mean is: " + sum_val / 5);
      
      
   }
      
  
}

import java.util.Scanner;

public class MyStatistics {

   public static void main(String[] args) {
       // TODO Auto-generated method stub

       Scanner sc = new Scanner(System.in);
       System.out.println("Please enter a group of at least 5 integers.");

       String count_val = sc.nextLine();
       int[] int_array = new int[5];
       int sum_val = 0;
       int mean_val = 0;
       System.out.println("Your input has " + count_val.split(" ").length + " numbers");

       // Input 5 Numbers
       // here your iterating 10 times because of that it is expecting 10 numbers
       //for (int x = 0; x < 10; x++) {
       for (int x = 0; x < 5; x++) {
           int_array[x] = sc.nextInt();
       }

       // Find the sum
       // here your iterating 10 times because of that it is expecting 10 numbers
       //for (int x = 0; x < 10; x++) {
       for (int x = 0; x < 5; x++) {
           sum_val = sum_val + int_array[x];
       }

       // Find the average
       for (int x = 0; x < 5; x++) {
           mean_val = sum_val + int_array[x];
       }

       System.out.println("The sum is: " + sum_val);
       System.out.println("The mean is: " + sum_val / 5);

   }

}
