Question

1. Create a text file called “Trivia.txt” that contains the contents of a trivia game, where the questions and answers are on separate lines. Example:

How many players are on a Baseball team?

Nine
What is the name of Batmans butler?

Alfred

Hg is the chemical symbol for what element?

Mercury

Create a program that reads the trivia questions from this text file, prints them out to netbeans and asks the user to input an answer. Compare the users answer to the correct answer on your text file. Provide an appropriate output letting the user know if they are correct, or if they are wrong what the correct answer should be.

Please help me code this in Java.

Answer 1

Code:

package demos;

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.Scanner;

public class demo49 {
   public static void main(String args[]) {
       ArrayList<String> questions = new ArrayList<String>();
       ArrayList<String> answers = new ArrayList<String>();
       int i=0;
       try {
       File myObj = new File("C:\\Users\\Anurag\\eclipse-workspace\\demos\\src\\demos\\Trivia.txt");
       Scanner myReader = new Scanner(myObj);
       while (myReader.hasNextLine()) {
       String data = myReader.nextLine();
       if(i%2==0)
           questions.add(data);
       else
           answers.add(data);
       i++;
       }
       myReader.close();
       }
       catch (FileNotFoundException e) {
       System.out.println("An error occurred.");
       e.printStackTrace();
       }
       Iterator<String> iterQues = questions.iterator();
       Iterator<String> iterAns = answers.iterator();
       Scanner sc = new Scanner(System.in);
       while(iterQues.hasNext() && iterAns.hasNext()) {
           String question = iterQues.next(), answer = iterAns.next();
          
           System.out.println(question);
           System.out.print("Ans: ");
           String givenAns = sc.nextLine();
           if(answer.equalsIgnoreCase(givenAns))
               System.out.println("Correct Answer.");
           else
               System.out.println("Wrong, the correct ans is: "+answer);
          
          
       }
       sc.close();
      
   }
}

Note: change the file location to where your file is.

Hope this helps.
