Question

Finish the program below that uses a nested loop to compute the sum, product, and average of rows of numbers given in input. The program will quit when the user inputs something that is not a number.

import java util. public class Lab5c public static void main (String args Scan the input Scanner scan [Your code here] Process each line separately If the next token is a double, assume there is an input line while (scan .hasNextDouble Get a line from the input String line [Your code here] Create a scanner for the line of input you have read Scanner linescan [Your code here] Write a while loop that will sum all of the double values on the line (hint: create double variables called "sum", product and "count". Set sum and count to 0, and product to 1 Then read as many double values as you can using the while loop When you read a number add it to sum, multiply product by it, and add 1 to count [Your code here] Compute the average by dividing sum by count [Your code here] Print out the sum, product, and average on one line [Your code here]

Explanation / Answer

import java.util.*;

public class Lab5c
{
   public static void main(String []args)
   {
       //Scan the input
       Scanner scan = new Scanner(System.in);
      
       //check if the next token in the input is a number or not
       while(scan.hasNextDouble())
       {
           // If the token is a number, then scan the entire line
           String line = scan.nextLine();

           //Scan the line for the numbers
           Scanner lineScan = new Scanner(line).useDelimiter("\s");
             
           //initialize the variables
           double sum = 0, product = 1, count = 0, average;
           try{
          
           //scan till the entire line from the input is read
           while(lineScan.hasNext())
           {
               double value = lineScan.nextDouble();
               sum = sum + value;
               product = product * value;
               count = count+1;
           }

           //calculate the average
           average = sum/count;

           //Print the sum, product and average values calculated above
           System.out.println("Sum = "+ sum + "Product = "+ product + "average = " + average);
           }
      
           //it catches an exception whenever an input which is not a number is encountered in the line.
           catch(Exception e)
           {
               System.out.println("Input which is not a number is found!! Please check.");
           }
          
       }
   }
}
