# Java Program to find the sum and average of array Elements

Get array size n and n elements of array, then compute sum and average of the elements.

Sample Input 1:

5 5 7 9 3 1

Sample Output 1:

25 5.0

#### Program or Solution

import java.util.*; class SAvArray { public static void main(String args[]) { int size,i,sum=0; double avg; Scanner sc=new Scanner(System.in); System.out.println("Enter Size Of Array:"); size=sc.nextInt(); int a[]=new int[size]; System.out.println("Enter The Array Elements:\n"); for(i=0;i<size;i++) { a[i]=sc.nextInt(); sum=sum+a[i]; } System.out.println("The Sum Of Array Elements Is:\n"+sum); avg=sum/size; System.out.println("The Average Is:"+avg); } }

#### Program Explanation

i is initialized to 0 and incremented by 1 at each iteration of both the for loops.

First for loop reads n input numbers from user and stores them in array a[] from location 0 to n-1 Second for loop adds all the n elements of array located from 0 to n-1 Finally compute average using avg=sum/n statement and prints average avg using system.out.println.
