Sum and Average the elements of an array for Java Example

Algorithm for Sum and Average the Elements:

step 1: set sum=0

step 2: read arr_size

step 3: create an integer array arr[] of size arr_size

step 4: initialize i=0

step 5: repeat through step-11 while i less than arr.length

step 6: read arr[i]

step 7: sum=sum +arr[i]

step 8: i=i+ 1

step 9: set avg=(float)(sum/ arr.length)

step 10: print avg

step 11: Exit

Here is the Java Example for Sum and Average the Elements:

 import java.util.Scanner; 
 public class ArraySumandAvg 
 { 
               public static void main(String args[]) 
         { 
               int sum=0; 
               Scanner s=new Scanner(System.in); 
               System.out.print("Enter The Size of the Array : "); 
               int size=s.nextInt(); 
               int arr[]=new int[size]; 
               System.out.println("Enter the elements of Array"); 
               for(int i=0;i<arr.length;i++) 
                  { 
                     arr[i]=s.nextInt(); 
                     sum+=arr[i]; 
                   } 
                     float avg=(float)(sum/arr.length); 
             System.out.println("Sum is "+sum+" Average is "+avg); 
         } 
 }
