Write a Java program that asks the user to input a positive

Write a Java program that asks the user to input a positive integer n first, then create an array of size n. Fill n random integer between 5 and 555, inclusively, into the created array. Output the sum of all the integers in the array and the average of all the integers in the array

Solution

package pkg;

import java.util.Scanner;
import java.util.Random;
import java.util.Arrays;
public class ReadFileExample1
{
public static void main(String[] args)
   {
       int[] numbers;
       int sum = 0, n;
       double avg;

       //Read the data from user(command)
       Scanner sc = new Scanner(System.in);
       System.out.println(\"Enter the size of an array\");
       n = sc.nextInt();

       numbers = new int[n];
       //List<Integer> ints = new ArrayList<Integer>();
       Random r = new Random();
       int Low = 5;
       int High = 555;
         
       //Generates 10 Random Numbers in the range 1 -20
       for(int i = 0; i < n; i++) {

       //Read the random value between 5 to 555
       int Result = r.nextInt(High-Low) + Low;   
      
       //store in an array
       numbers[i] = Result;

       //calcuate the sum
       sum += Result;
       }//end for loop

       //calcuate the average
       avg = sum / n;

       System.out.println(\"Numbers Generated: \" + Arrays.toString(numbers));
       System.out.println(\"Sum: \" + sum);
       System.out.println(\"Average: \" + avg);

   } // end main
