Java Program to Calculate Average of Nth Float Numbers in An Array

java program to calculate average of nth float numbers in an array. User enter size or length of an array and after enter, any element of an array, any element means float number or integer number then calculate average of number.

import java.util.*;
class average
{
    public static void main(String[] args) 
    {
        float average,sum=0;
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter length of an array :");
        int len = sc.nextInt();
        float n[] = new float[len];
        System.out.println("Enter all the elements of an array:");
        for(int i=0;i<len;i++)
        {
            n[i] = sc.nextFloat();
            sum = sum + n[i];
        }
        average = sum / len;
        System.out.println("Average:"+average);
    }
}

Output :

Enter length of an array :3
Enter all the elements of an array:
5.5
2.5
1
Average:3.0
