What is the solution to this, please make sure code is ready to be copied. Thank you. The text version of this is below.

public class ArraysLabInt{

//maxElement returns the max value in the array arr

static int maxElement(int [] arr){ return 0; }

//averageVal returns the average of all the values

static double averageVal(double [] arr){ return 0.0; }

/*everyFourth returns an array arr but... each multiple of 4 is replaced by 1111*/static int [] everyFourth(int [] arr) { return arr; }

//populateGrades returns an array of doubles that represent 8 grades. //The user should be inputting these grades from the scanner //The user input should be done within the structure of the method, not within Mainstatic double [] populateGrades() { double [] arr = {}; return arr; }

Exercise 1: public class ArraysLablnt /maxElement returns the max value in the array arr static int maxElement(int ] arrX return 0; ) //averageVal returns the average of all the values static double averageVal(double [| arr) return 0.0; ) /*everyFourth returns an array arr but... each multiple of 4 is replaced by 1111* static int everyFourth (int ] arr) return arr; h /populateGrades returns an array of doubles that represent 8 grades. //The user should be inputting these grades from the scanner //The user input should be done within the structure of the method, not within Main static double I populate Grades() { double arr return arr; ) Exercise 1: Results Example Array arr - 1, 2, 8, 4, 3, 7, 4, 2 Max Element maxElement (arr) 8 Average Value averageVal(arr) - 3.875 Every Fourth everyFourth(arr) - Populate Grades Arr before populateGrades (arr) - t0, 0, 0, 0, e, 0, 0, 0 Arr after populateGrades (arr) - 190, 80, 55, 76, 82, 86, 93, 921
