Java-Quiz

An interactive quiz game developed in Java, showcasing fundamental concepts, JavaFX for the user interface, and Java features such as file I/O and multithreading.

Features

Core Functionality

• Conditionals:
  • Game logic uses if/else statements for handling answers and timer logic.
• Inheritance:
  • Demonstrates base (Game) and child (QuizGame, MultipleChoiceQuestion, TrueFalseQuestion) classes.
• Polymorphism:
  • Uses a Game reference to handle instances of QuizGame, and a Question reference for different types of questions.
• Exception Handling:
  • Gracefully handles invalid input, file I/O issues, and notifies the user.
• Multithreading:
  • Implements a countdown timer using background threads.

Interactive UI

• Built using JavaFX.
• Presents questions with interactive multiple-choice and true/false options.
• Real-time countdown timer displayed on the UI.
• Score for correct/incorrect answers is shown at the end fo the game.

File I/O

• Reads questions from a file (questions.txt).
• Saves high scores to a file (highscores.txt).

Prerequisites

• git 2
• maven 3
• JDK 21
• OpenJavaFX 21
