I am making a quiz where one can choose from 3 different titles: either plate tectonics, rivers or rocks. I typed the questions in a textfile and i stored the answers in an array. My problem is that i wish to display the questions randomly, and not always in the same format. What can i do? Thanks a lot for the help. I appreciate it a lot! This is the code i have written: Code: import java.awt.*; import java.awt.event.*; import java.util.*; import java.io.*; import javax.swing.*; public class GQ 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; AnswerStore answerStore = new AnswerStore(); public static void main (String[] args) { JOptionPane.showMessageDialog(null, "This is a Geography Quiz"); JOptionPane.showMessageDialog(null, "Good Luck"); GQ frame = new GQ(); frame.setVisible(true); } public GQ() { 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) { String ac = e.getActionCommand(); String[] questions = null; String[] answers = null; if (ac.equals("b1")) { questions = readFile("plate_tectonics.txt"); answers = answerStore.tectonicAnswers; } else if(ac.equals("b2")) { questions = readFile("rivers.txt"); answers = answerStore.riverAnswers; } else if(ac.equals("b3")) { questions = readFile("rocks.txt"); answers = answerStore.rockAnswers; } else if (ac.equals("b4")) { System.exit(0); } askQuestions(questions, answers); } private String[] readFile(String path) { Scanner s = null; StringBuilder sb = new StringBuilder(); String separator = "\n"; try { s = new Scanner(new BufferedReader(new FileReader(path))); // s.useDelimiter(",\\s*"); while (s.hasNext()) { sb.append(s.nextLine() + separator); // JOptionPane.showMessageDialog(null,s.next()); } } catch(IOException e) { System.out.println("read error: " + e.getMessage()); } finally { if (s != null) s.close(); // break; } } private void askQuestions(String[] questions, String[] answers) { System.out.printf("questions = %s%nanswers = %s%n", Arrays.toString(questions), Arrays.toString(answers)); int count = 0; int point = 0; for(int j = 0; j < questions.length; j++) { String input = JOptionPane.showInputDialog(null, questions[j]); if(answers[j].equals(input)) { count++; point++; } } JOptionPane.showMessageDialog(null, "You answered " + count + " out of " + questions.length + " questions correctly."); JOptionPane.showMessageDialog(null, "Your Geography Quiz score is " + ((point*100)/10) + " % "); if(point>=0 && point<=3) { JOptionPane.showMessageDialog(null, "You need to Improve"); } if(point>=4 && point<=7) { JOptionPane.showMessageDialog(null, "Good"); } if(point>=8 && point<=10) { JOptionPane.showMessageDialog(null, "You did Great"); } } } class AnswerStore { String[] tectonicAnswers = { "Hellenic", "destructive", "100km", "Italy", "Wegner", "Mariana", "Sicily", "created", "constructive", "Mediterranean" }; String[] riverAnswers = { "Gorges", "Meanders", "Levees", "Yes", "Less Economic Developed Countries", "crescent shaped lakes", "More Economic Developed Countries", "No", "River Discharge", "No" }; String[] rockAnswers = { "40km", "Igneous Rock", "Sedimentary", "Basalt", "Organic", "pressure", "Oolites", "Igneous", "dark black", "basalt" }; } Thanks again!
i don't know java but i think it is a logical question ..could u just post the fomat of your question files.. i believe a solution can be found after that.
