Average an array)
Write two overloaded methods that return the average of an array with the following headers:
public static int average(int[] array)
public static double average(double[] array)
Write a test program that random generate ten integers between 0 – 100, and ten double values between 0 – 50. Invokes both methods, and displays all values and the average values. (All double numbers will be displayed with twodigit decimal places.)
as i have done somewhat but, still there is error in it. please solve this problem according to the question.

Best ResponseYou've already chosen the best response.0Thanx for your kind help but m still confused... i did something which is as follows ackage intdouble; /** * * @author JAY */ import static java.lang.Math.random; import java.util.Scanner; import java.util.Random; //import java.util.Random.nextint; public class IntDouble { public static int average(int[] array) { int sum = 0; int average = 0; for (int i = 0; i < array.length; i++) { random rn= new random(); sum += random.nextInt(100); } average = sum / array.length; return average; } public static double average(double[] array) { double sum = 0; double average = 0; for (int i = 0; i < 5; i++) { sum += random.nextInt(50); } average = sum / array.length; return average; } public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter Integer values: "); int array1[] = new int[4]; for (int i = 0; i < array1.length; i++) { array1[i] = input.nextInt(); } int avg1 = average(array1); System.out.println("Average of First Array: " + avg1); System.out.println(); System.out.print("Enter Ten Double Values: "); double array2[] = new double[10]; for (int i = 0; i < array1.length; i++) { array2[i] = input.nextDouble(); } double avg2 = average(array2); System.out.println("Average of Second Array: " + avg2); } }

Best ResponseYou've already chosen the best response.0This is waht i did.. but it ask for number.. but i want to genrate the number randomly for both integer and double and and last it has to show those 10 random numbers.. Please complete this program... i am posting it again /* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools  Templates * and open the template in the editor. */ package intdouble; /** * * @author JAY */ import static java.lang.Math.random; import java.util.Scanner; import java.util.Random; //import java.util.Random.nextint; public class IntDouble { public static int IntDouble(int[] array) { int sum = 0; int average = 0; Random rn= new Random(); for (int i = 0; i < array.length; i++) array[i] = rn.nextInt(101); sum += Random.nextInt(100); average = sum / array.length; return average; } public static double IntDouble(double[] array) { double sum = 0; double average = 0; { Random rn= new Random(); for (int i = 0; i < 5; i++) array[i] = rn.nextInt(101); //sum += Random.nextInt(50); } average = sum / array.length; return average; } public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter Integer values: "); int array1[] = new int[10]; for (int i = 0; i < array1.length; i++) { array1[i] = input.nextInt(); } int avg1 = IntDouble(array1); System.out.println("Average of First Array: " + avg1); System.out.println(); System.out.print("Enter Ten Double Values: "); double array2[] = new double[10]; for (int i = 0; i < array1.length; i++) { array2[i] = input.nextDouble(); } double avg2 = IntDouble(array2); System.out.println("Average of Second Array: " + avg2); } }
