JAVA QUESTION

Ex 17: Average Scanner Started: May 20 at 11:08pm Quiz Instructions D Question 1 1 pts Write a method averageScanner that reads in double values from an argument Scanner as long as the Scanner indicates that there is a double value to read. The method returns a double indicating the average (mean) of the double values provided by the Scanner. You may assume the Scanner provides at least one double value.

Answer 1

Java program:

import java.util.Scanner;

public class AverageFinder

{

//class variables to hold data

static double sum=0,avg=0;

static int count=0;

//main method

public static void main(String[] args)

{

//Scanner class object to read values

Scanner in = new Scanner(System.in);

System.out.println("Enter double values,-1 to quit");

double values=0;

  

//while loop to enter values till input is -1

while((values= in.nextInt()) != -1)

{

//calling method

avg=averageScanner(values);

}

//printing the output to console

System.out.println("Average="+avg);

}

//method reading double values from scanner and returning mean

public static double averageScanner(double values)

{

//summing the values

sum=sum+values;

//to count number of values read in

count++;

//finding average

avg=sum/count;

//returning average

return avg;

}

}
