Java Program:

import java.util.Random;

public class Main

{

public static void main(String[] args)

{

int N, L, U;

N = Integer.parseInt(args[0]);

L = Integer.parseInt(args[1]);

U = Integer.parseInt(args[2]);

int arr[] = new int[N];

Random rand = new Random();

for(int i=0; i<N; i++)

arr[i] = rand.nextInt(U-L) + L;

double sum = 0;

for(int i=0; i<N; i++)

sum += arr[i];

double avg = sum/N;

int below, above, equal;

below = above = equal = 0;

for(int i=0; i<N; i++)

if(arr[i] == avg)

equal++;

else if(arr[i] > avg)

above++;

else

below++;

System.out.println(“Average = ” + avg);

System.out.printf(“%2d elements are below the averagen”, below);

System.out.printf(“%2d elements are above the averagen”, above);

System.out.printf(“%2d elements are equal to the averagen”, equal);

}

}

Instructions:

Save the Program as Main.java
