Question

Create an application containing an array that stores 10 integers. The application should call five methods that in turn:

(1) display all the integers

(2) display all the integers in reverse order

(3) display the sum of the integers

(4) display all values less than a limiting argument

(5) display all values that are higher than the calculated average value.

Then, create another array that store 5 integers.

Pass the two arrays to a method that will display the integer value(s), if any, that appear in both arrays (note that the two arrays can have no stored values in common).

public class ArrayMethodDemo {

   private static void displayAllIntegers(int arr[]) {
       for (int i = 0; i < arr.length; i++) {
           System.out.print(arr[i] + " ");
       }
       System.out.println("");
   }

   private static void displayAllIntegersInReverese(int arr[]) {
       for (int i = arr.length - 1; i >= 0; i--) {
           System.out.print(arr[i] + " ");
       }
       System.out.println("");
   }

   private static int sumOfAllIntegers(int arr[]) {
       int count = 0;
       for (int i = 0; i < arr.length; i++) {
           count += arr[i];
       }
       System.out.println(count);

return count;
}

   private static void displayAllIntegersLessThanLimit(int arr[], int limit) {
       for (int i = 0; i < arr.length; i++) {
           if (arr[i] < limit) {
               System.out.print(arr[i] + " ");
           }
       }
       System.out.println("");
   }

   private static void displayAllElementsBelowAverage(int arr[]) {
       int avg = sumOfAllIntegers(arr) / arr.length;
       displayAllIntegersLessThanLimit(arr, avg);
   }

   private static void intersection(int arr10[], int arr5[]) {
       for (int i = 0; i < arr5.length; i++) {
           for (int j = 0; j < arr10.length; j++) {
               if (arr5[i] == arr10[j]) {
                   System.out.print(arr5[i] + " ");
               }
           }
       }
       System.out.println("");
   }

   public static void main(String[] args) {
       int arr10[] = new int[10];
       int arr5[] = new int[5];

       for (int i = 0; i < 10; i++) {
           arr10[i] = i + 1;
       }
       for (int i = 0; i < 5; i++) {
           arr5[i] = i + 7;
       }

       displayAllIntegers(arr10);
       displayAllIntegersInReverese(arr10);
       sumOfAllIntegers(arr10);
       displayAllIntegersLessThanLimit(arr10, 6);
       displayAllElementsBelowAverage(arr10);
       intersection(arr10, arr5);
   }
