Hi i'm doing a quiz using java. I have wrote the questions in a textfile and i called them from Java. But now my problem is about the answers. i stored the answers in another class, and i used arrays to store the answers. Now what i'm having trouble with is, that when the user enters the answer i want to compare the answer with the correct answer so that if he/she answers correctly i would display correct else it would display incorrect. Can someone pls help, by showing me how to compare the answers. I tried using if condition but i diddn't know what conditions i had to compare. Thanks a lot for the help.

This is the code i have written:

Code:

import java.awt.*;
import java.awt.event.*;
import java.util.*;

import java.io.*;

import java.util.Scanner;
import java.util.Arrays;

public class GeographyQuiz extends JFrame implements ActionListener {

  private static final int FRAME_WIDTH = 140;
  private static final int FRAME_HEIGHT = 160;
  private static final int FRAME_X_ORIGIN = 70;
  private static final int FRAME_Y_ORIGIN = 50;

  public static void main (String[] args) {

    JFrame jFrame;
    jFrame = new JFrame();

    JOptionPane.showMessageDialog(jFrame, "This is a Geography Quiz");
    JOptionPane.showMessageDialog(null, "Good Luck");

    char choice;
    int i, choice1, Password;
    String yourChoice, passString;

    passString = JOptionPane.showInputDialog("Enter the Password");

    //Password = passString.nextInt();
    Password = Integer.parseInt(passString);

    if (Password == 123) {
     JOptionPane.showMessageDialog(null, "Valid. You typed the right password. Now choose from the following menu");

     GeographyQuiz frame = new GeographyQuiz();
      frame.setVisible(true);

    } else {
      JOptionPane.showMessageDialog(null, "Invalid Password. Try Again");
    }
  }

  public GeographyQuiz() {
    Container contentPane;
    JButton button1, button2, button3, button4, button5;

    setSize (FRAME_WIDTH, FRAME_HEIGHT);
    setTitle("Geography Quiz");
    setLocation(FRAME_X_ORIGIN, FRAME_Y_ORIGIN);

    contentPane = getContentPane();
    contentPane.setBackground(Color.pink);
    contentPane.setLayout(new FlowLayout());

    button1 = new JButton("Plate Tectonics");
    button2 = new JButton("Rivers");
    button3 = new JButton("Rocks");
    button4 = new JButton("Quit");

    contentPane.add(button1);
    contentPane.add(button2);
    contentPane.add(button3);
    contentPane.add(button4);
    
    button1.addActionListener(this);
    button1.setActionCommand("b1");
    button2.addActionListener(this);
    button2.setActionCommand("b2");
    button3.addActionListener(this);
    button3.setActionCommand("b3");
    button4.addActionListener(this);
    button4.setActionCommand("b4");

    setDefaultCloseOperation(EXIT_ON_CLOSE);

  } 
  
   public void actionPerformed(ActionEvent e) {

    if ("b1".equals(e.getActionCommand())) {
    
       Scanner s = null;
         try {
        s = new Scanner(new BufferedReader(new FileReader("plate_tectonics.txt")));

        while (s.hasNext()) {
          s.useDelimiter(",\\s*");
          JOptionPane.showInputDialog(null,s.nextLine());
          
          JOptionPane.showMessageDialog(null, "Correct");
        }
      
      } catch (java.io.FileNotFoundException f) {
        JOptionPane.showMessageDialog(null, "File not found.");
    
      } finally {
        if (s != null)
          s.close();
      }
    
    } else if("b2".equals(e.getActionCommand())) {
    
       Scanner s = null;
         try {
        s = new Scanner(new BufferedReader(new FileReader("rivers.txt")));

        while (s.hasNext()) {
          s.useDelimiter(",\\s*");
          JOptionPane.showInputDialog(null,s.nextLine());
        }
      
      } catch (java.io.FileNotFoundException f) {
        JOptionPane.showMessageDialog(null, "File not found.");
    
      } finally {
        if (s != null)
          s.close();
      }
    
    } else if("b3".equals(e.getActionCommand())) {
    
       Scanner s = null;
         try {
        s = new Scanner(new BufferedReader(new FileReader("rocks.txt")));

        while (s.hasNext()) {
          s.useDelimiter(",\\s*");
          JOptionPane.showInputDialog(null,s.nextLine());
        }
      
      } catch (java.io.FileNotFoundException f) {
        JOptionPane.showMessageDialog(null, "File not found.");
    
      } finally {
        if (s != null)
          s.close();
      }
    
    } else if ("b4".equals(e.getActionCommand())) {
        System.exit(0);
    
    }  
  }
}

And this is the other class which stores the anwers to the questions in an array:

Code:

import java.util.*;

public class Answer  {

public static void main (String[] args) {

  String[] answer = new String[10];
  
  answer[0] = "Hellenic";
  answer[1] = "constructive";
  answer[2] = "100km";
  answer[3] = "Italy";
  answer[4] = "Wegner";
  answer[5] = "constructive";
  answer[6] = "100km";
  answer[7] = "Italy";
  answer[8] = "destroyed";

}
}
