Question
Java: 

Implement the ArrayMethodDemo application containing an array that stores eight integers. The application should call the following five methods:

  1. display - should display all the integers
  2. displayReverse - should display all the integers in reverse order
  3. displaySum - should display the sum of the integers
  4. displayLessThan - should display all values less than a limiting argument
  5. displayHigherThanAverage - should display all values that are higher than the calculated average value.
Code:
public class ArrayMethodDemo {
    public static void main (String args[]) {
        int[] numbers = {12, 15, 34, 67, 4, 9, 10, 7};
        int limit = 12;
        display(numbers);
        displayReverse(numbers);
        displaySum(numbers);
        displayLessThan(numbers, limit);
        displayHigherThanAverage(numbers);
    }
    public static void display(int[] numbers) {
        // Write your code here
    }
    public static void displayReverse(int[] numbers) {
        // Write your code here
    }
    public static void displaySum(int[] numbers) {
        // Write your code here
    }
    public static void displayLessThan(int[] numbers, int limit) {
        // Write your code here

    }
    public static void displayHigherThanAverage(int[] numbers) {
        // Write your code here
