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

### Description

```Get array size n and n elements of array, then compute sum and average of the elements.
Input:
5
5 7 9 3 1
Output:
25
5.0```

### 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);

}
}```

### 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.```
