Write a Java program to accept N array Elements and calculate Sum and Average of array elements.

Write a Java program to accept N array Elements and calculate Sum and Average of  array elements.

program:

import java.util.Scanner;
public class Array_Sum
{ 
public static void main(String[] args)
{
int n, sum = 0; 
float avg;
Scanner sc= new Scanner(System.in); System.out.print("Enter no. of elements you want in array:");
n = sc.nextInt();

int a[] = new int[n];
//int a[ ]={10,50,20,40,30};
System.out.println("Enter all the elements:"); 
for(int i = 0; i < n; i++)
{
a[i] = sc.nextInt();
sum = sum + a[i];
}

System.out.println("Sum is:"+sum);
avg=(float)sum/n;
System.out.println("Average is:"+avg);
}
}

Output:

Enter no. of elements you want in array :
5 
Enter all the elements: 
1
2
3
4
5
Sum is:15
Average is:3.0
