Question

for Qustion number 5.

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

public class HoursWorked2 {

   public static void main(String[]args)

           throws FileNotFoundException{

           Scanner input = new Scanner(new File("hours2.dat"));

           while(input.hasNextLine()){

           String text = input.nextLine();

           processLine(text);

      

   }

}

   public static void processLine(String text) {

       Scanner data = new Scanner(text);

       int id = data.nextInt();

       String name = data.next();

       double sum = 0.0;

       while (data.hasNextDouble()) {

           sum+= data.nextDouble();

          

       }

       System.out.println("Total hours worked by " + name + " (id#" + id + " = " + sum);

   }

}

Question 5 1.5 pts Which of the following statements CORRECTLY describe the program HoursWorked2 listed on pp 414-415? Check all that apply. On line 18, the Scanner object is constructed out of a string. Each line is stored as a string. The file is read line by line. Overall, a file is processed using token-based processing and then each token is processed using line-based processing O Each string is passed to another method called processString Question 6 1.5 pts Which of the following statements are TRUE? Check all that apply. When using files with PrintStream objects, Java convention requires that you write a throw statement in the header of a method containing File and PrintStream declarations. In order to write to files a PrintStream object needs to be constructed and connected to the particular file to be written. PrintStream output new PrintStream("results.txt"); shows correct syntax for constructing a PrintStream object. Once a PrintStream object is constructed and associated with a file, one can use System.out methods like println and print to write to it.

Explanation / Answer

Answer :

b. Each line is stored as a String
c.The file is Read line by line



Explanation : d is false because each line is passed to processLine and not processString.
c is false because file is processed using line based processing.


Answer: a, b is True
c is True
