Java program problem

Question

Hi! I'm learning java for about 2 months and I tried to do a quiz from a file. I tried hard, but now I don't know what did I wrong and what should I do. The file (notepad) quiz has first line to question, four next lines are the answers and next line is a correct answer. That's like 3 times. Yes, I know, my code is really "dirty", but I've scarcely started we can say. Thanks in advance and there is the code:

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

public class Main {
public static void main(String[] args) throws FileNotFoundException {

String fileName = "C:\\Users\\patry\\Desktop\\scanner.txt";
File textFile = new File(fileName);

Scanner in = new Scanner(textFile);

int counter = 0;
int points = 0;
Scanner scan = new Scanner(System.in);

LinkedList<String> answers = new LinkedList<>();
LinkedList<String> correctAnswers= new LinkedList<>();

while(in.hasNextLine()){

String line = in.nextLine();

System.out.println(line);

if(counter == 4|| counter == 10 || counter == 16){
System.out.print("Your answer: ");
answers.add(scan.next());
in.nextLine();
counter++;

}

if(counter == 5|| counter == 11 || counter == 17)
correctAnswers.add(line);

counter++;
}
Iterator<String> it = answers.iterator();
Iterator<String> it1 = correctAnswers.iterator();
while(it.hasNext()){

if(it.next().equals(it1.next()))
points++;
}

System.out.println("U've got "+ points + " point(s)! Congratulations!");
}
}

P.S. This code almost works, but It just chooses the answer 'd' everytime as a correct answer, the file looks like it:
Question1
a
b
c
d
b
Question2
a
b
c

Answer 1

In your first if statement:
if(counter==4...
the line,
in.nextLine();
is not saved into the variable line for use in the next if statement.
You could remove that line and just do;
correctAnswers.add(in.nextLine());
There may be more, but that is what I can see at first glance.

Answer 2

I dont try to read a similar code... Exist an useful feature like 'Code Playground' section... Use it (Save your code in that section and post his link here)
