Java program to accept n elements in array and find its sum and Average

Write a java program to accept n elements in array and find its sum and Average.

import java.util.*;
class SumAvg
{
    public static void main(String arr[])
    {
        Scanner sc=new Scanner(System.in);        
        System.out.println("Enter the size of Array : ");
        int n=sc.nextInt();
        int num[]=new int[n];
        int sum=0;
        float avg;
        System.out.println("Enter the "+n+" Elements of Array");
        for(int i=0;i<n;i++)
        {
            num[i]=sc.nextInt();
        }
        System.out.println("Array Elements Are : ");
        for(int i=0;i<n;i++)
        {
            System.out.print(num[i]+" ");
            sum=sum=num[i];
        }
        avg=(float)sum/n;
        System.out.println("\nSum of All Elements :"+sum);
        System.out.println("Avg of All Elements :"+avg);
    }
}

Enter the size of Array : 

5

Enter the 5 Elements of Array

3

4

5

3

4

Array Elements Are : 

3 4 5 3 4 

Sum of All Elements :4

Avg of All Elements :0.8
