1. Write a method that returns an int array using user's inputs from the console window. The method should have the following header. The formal parameter size is the size of the return array. public static int[] inputArray (int size) 2. Write a method that calculates and returns the average of an array with the following headers. public static double average (int[] list) 3. Write a method to add two int arrays, assuming that arrays referred by variables a and b are of the same size. The header of the method is as follows. public static int[] add (int[] listl, int[] list2) The add method should return an array of the same size as the input arrays, with each element to be the sum of the elements from the input arrays. For example, if the two input arrays are [3, 5, 2, 6, 4, 9] and [1, 2, 3, 4, 5, 6], the returned sum array should be [4, 7, 5, 10, 9, 15]. 4. Write a method to display an int array's contents on the console window. The header of the method is as below. public static void displayArray (int[] list) 5. Write the main method to: a. Create two input arrays with the same size by invoking the inputArray method twice in the main method. b. Calculate the average of the first int array by invoking the average method. Display the average result on the console window. c. Calculate the array sum of both input arrays by invoking the add method. d. Display the sum array by invoking the display Array method.

Need help writing the code. Attatching the problem instruction and code outline and display result in the images.
![1. Write a method that returns an int array using user's inputs from the console window. The
method should have the following header. The formal parameter size is the size of the return
array.
public static int[] inputArray (int size)
2. Write a method that calculates and returns the average of an array with the following headers.
public static double average (int[] list)
3. Write a method to add two int arrays, assuming that arrays referred by variables a and b are
of the same size. The header of the method is as follows.
public
static int[] add (int[] list1, int[] list2)
The add method should return an array of the same size as the input arrays, with each
element to be the sum of the elements from the input arrays. For example, if the two input
arrays are [3, 5, 2, 6, 4, 9] and [1, 2, 3, 4, 5, 6], the returned sum array should be [4, 7, 5, 10,
9, 15].
4. Write a method to display an int array's contents on the console window. The header of the
method is as below.
public static void displayArray (int[] list)
5. Write the main method to:
a. Create two input arrays with the same size by invoking the inputArray method twice
in the main method.
b. Calculate the average of the first int array by invoking the average method. Display
the average result on the console window.
c. Calculate the array sum of both input arrays by invoking the add method.

3. Write a method to add two int arrays, assuming that arrays referred by variables a and b are
of the same size. The header of the method is as follows.
public
static int[] add (int[] list1, int[] list2)
The add method should return an array of the same size as the input arrays, with each
element to be the sum of the elements from the input arrays. For example, if the two input
arrays are [3, 5, 2, 6, 4, 9] and [1, 2, 3, 4, 5, 6], the returned sum array should be [4, 7, 5, 10,
9, 15].
4. Write a method to display an int array's contents on the console window. The header of the
method is as below.
public static void displayArray (int[] list)
5. Write the main method to:
a. Create two input arrays with the same size by invoking the inputArray method twice
in the main method.
b. Calculate the average of the first int array by invoking the average method. Display
the average result on the console window.
c. Calculate the array sum of both input arrays by invoking the add method.
d. Display the sum array by invoking the displayArray method.
![public static void main(String[] args) {
int[] arr1 = inputArray (?); // Enter any input array size for testing
int[] arr2 = inputArray (?); // Enter the same input array size for
// testing
//Prints the average of the elements in the first array.
System.out.println("The average of the first array provided is "
/*Please write your code here*/ + "-");
//Creates an array that holds the value of the sums from adding the two
//integer arrays.
int[] resultingArray = add(arr1, arr2);
//Prints the array with the sum of the two added integer arrays.

//Creates an array of size provided.
int[] inputArr = new int [size];
//Asks user to input values for elements to be.

}
public static void display Array(int[] list) {
System.out.println("The sum resulting array is " +
/*Please write your code here*/);
}
Finally, your code's formatting should look exactly like the output mentioned below and
should be able to run test cases on different values of 'size'.
