Trying to build trivia game with questions from a file, having some issues

I am trying to build a 2-4 player trivia game using questions from a text file and I am stuck on getting the questions from the text file to add to my array list. It seems like I can only get the first question to add and no matter where I try to change my counter, I get an out of bound exception. Can anyone give me some insight on how to make this work? I want to be able to move to the next question.

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

public class Questions {

    private ArrayList<String> theQuestions;
    private int current; //current question you're asking
    private int next;


    public Questions(){ //make this the default constructor
        current = 0; //haven't asked any questions yet

        String fileName = "triviaquestions.txt";
        File inputFile = new File(fileName);
        Scanner inFile = null;
        String[] pieces = null;

        //Checked exception - java is forcing you to deal with this.
        try {
            inFile = new Scanner(inputFile);
        }
        catch (FileNotFoundException ex){
            System.out.println("No such file exists.");
            System.exit(0);
        }

        //setup arrayList to hold questions
        theQuestions = new ArrayList<>();        

        try {
            while (inFile.hasNextLine()){
                String line = inFile.nextLine();
                //Only adding first line of file to arrayList...why?
                theQuestions.add(line);
            }
        }
        catch (ArrayIndexOutOfBoundsException ex){
            System.out.println("The file format is incorrect.");
        }
        catch (InputMismatchException ex){
            System.out.println("The file format is incorrect.");
        }
        finally {
            inFile.close();
        }
    }

    //This splits the first question, how do I get to the next question?
    public void getQuestion(){
        //Split question here
        System.out.println(theQuestions.get(current));
        String[] pieces = theQuestions.get(current).split("\\|");

        for (int i = 0; i <= 4; i++){
            System.out.println(pieces[i]);
        }
    }

    public void theAnswer(){
        System.out.println(theQuestions.get(current));
        String[] pieces = theQuestions.get(current).split("\\|");

        for (int i = 0; i <=0; i++){
            String answer = pieces[5];
            System.out.println(answer);
        }
    }
}
