Sum and Average of 5 Numbers

Write a program in Java to input 5 numbers from the keyboard and find their sum and average.

Test Data
Input the 5 numbers: 1 2 3 4 5

Pictorial Presentation:

Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise12 {

    
  public static void main(String[] args)

{       
    int i,n=0,s=0;
	double avg;
	{
	   
        System.out.println("Input the 5 numbers : ");  
         
	}
		for (i=0;i<5;i++)
		{
		    Scanner in = new Scanner(System.in);
		    n = in.nextInt();
		    
  		s +=n;
	}
	avg=s/5;
	System.out.println("The sum of 5 no is : " +s+"\nThe Average is : " +avg);
 
}
}

Sample Output:

Input the 5 numbers :                                                                                         
1                                                                                                     
2                                                                                                     
3                                                                                                     
4                                                                                                     
5                                                                                                     
The sum of 5 no is : 15                                                                                       
The Average is : 3.0
