Java program to find the average of given numbers using arrays

You can read data from the user using scanner class.

Using the nextInt() method of this class get the number of elements from the user.
Create an empty array.
Store the elements entered by the user in the array created above.
Finally, Add all the elements in the array and divide the sub by the number of elements.

Example

import java.util.Scanner;
public class AverageUsingArrays {
   public static void main(String args[]){

      //Reading total no.of elements
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter the number of elements/numbers");
      int num = sc.nextInt();

      //Creating an array
      int[] myArray = new int[num];

      //Read numbers from user and store it in an array
      System.out.println("Enter the numbers one by one : ");
      System.out.println("Press Enter button after each number : ");

      for(int i =0; i<num; i++){
         myArray[i] = sc.nextInt();
      }

      //Calculate the average
      double average = 0;
      for(int i =0; i<num; i++){
         average = average + myArray[i];
      }

      average = average/num;
      System.out.println("Average of given numbers :: "+average);
   }
}

Output

Enter the number of elements/numbers
5
Enter the numbers one by one :
Press Enter button after each number :
55
66
55
55
