Prompts the user for the:

output file name

array size

numbers in array

Expected output is incouded

Write an interactive program that displays statistics about an array of randomly generated integers. The program will also Save the output to a file First your program should display an introduction Second your program should prompt for the name of an output file to use Now, in a loop until the user chooses to quit: s o inclusive. If the uscenters a prompt the user for a size for the array of inters. The range of value that is not in the valid range, give an error message and pota After obtaining a valid size from the sce, your program will the array will be the value previously input by the user. The inclusive any of tandem integer. These of designs should be in the range-5 to 5 Your program should the display the following on the console m ple: 12.-3.3.1.6 The numbers in the way inside square brackets and separated by co The minimum value in the way. (an int) The maximum value in the array, (an int) The sum of the numbers in the array. Canin The average of the numbers in the wounded to decimal place d The median of the numbers in the army rounded to decimal places d (The median of a sorted array of odd length is the middle ) The median of a sorted array of even length is the average of the det e es sept for this Use print for this) e rs) Your program should repeat until the user enters as the size of the amy l is a scend to quit the program) Your program will be divided into two separate java files: "Numbers.Mainjasad Numbers java Numbers.

The methods should work with an array o n Note: Numbers.java will not do any 1/0. That is, it should not have any print statements or read or write any files. It should not prompt for user input. Note: You MUST NOT change the method signatures shown above. You may provide additional methods to help structure your code if you wish. Note: The statistical calculation methods in Numbers.java must work with an unsorted array as a parameter. These methods may need to sort a copy of the numbers array to do some of the calculations, but should not alter the original array in any way. These methods should return full precision results, not rounded results, Extra Credit 5%: Also display the standard deviation of the numbers in the array. You would accomplish this by providing an additional method in Numbers.java: public static double calculateStandardDeviation (int[] integers) Here is the formula for population standard deviation: sa.length-1 (ali) - average(a) LEO stdDev(a) = a. length Sample output (user input in bold): This program prompts for an array size between 3 and 8 inclusive. The program then creates an array of that size and fills it with random integers. The program then displays statistics about the array of integers. The program also saves the output to a file. Enter the name of the output file to use : outputA.txt Enter the size of the array (3 to 8; -1 to quit): 3 Here is the random array: [1, -5, -4) Minimum value: -5 Maximum value: 1 The sum of the numbers is: -8 The average of the numbers is: -2.67 The median value is: -4.00 The standard deviation is: 3.21 Enter the size of the array (3 to 8; -1 to quit): 5 Here is the random array: (-1,-1,-4, 2, 1) Minimum value: -4 Maximum value: 2 The sum of the numbers is: -3 The average of the numbers is: -0.60 The median value is: -1.00 The standard deviation is: 2.30 Enter the size of the array (3 to 8; -1 to quit): -4 The size of the array must be 3 to 8. Please try again. Enter the size of the array (3 to 8; -1 to quit): hello Not an integer; try again. Enter the size of the array (3 to 8; -1 to quit): -1 Thanks for trying the 'Random Integer Array' program! NOTE: Notice in the output above that the array of numbers is NOT sorted. You should display the array of integers in the order in which they are randomly created
