Random grades 1 and 2:

(RandomGrades) Using built-in arrays, create the program and associated methods described below. Part A: Using the random method in the Math class, create a program that creates an array of specified size comprised of random integer grades from 0..100. Then display the grades in the order they appear in the array. Part B: Write a method reverseArray(x) that will reverse the elements of array x. Then display the reversed array. Your method must physically reverse the array not simply display them in reverse order. Part C: Write four (4) additional methods, sum (x), average (x),min(x), and max (x) that will return the sum, average, minimum element, and maximum element from array x, respectively. All should have return type int except average which should return a double. Your main program should call these methods to display the resulting values for the random array selected in part A. Sample Output: 78, 45, How many grades would you like? 5 PART (A): Construct a random array. Grades: 20, 54, 45, 100 PART (B): Reverse the array. Grades: 100, 54, 78, 20 PART (C): Display SUM, AVG, MIN, and MAX. Sum of grades - 297 Average of grades = 59.40 Minimum grade 20 Maximum grade 100 (RandomGrades 2) Using an ArrayList, create the program and associated methods that duplicates the behavior of RandomGrades above.
